I've been giving this a look and it seems that we aren't building the
advanced virt modules because CentOS builds them from upstream?

I've found no mention of them in their Pagure, and they're built on
their Community Build System via a SIG, with the metadata set on them
as `Extra: {'source': {'original_url': 'libvirt-7.0.0-
14.1.el8.src.rpm'}}`.

My colleague Neil looked into it, and concluded it seems to be a CLI
build being manually run(?).

We could investigate building that, but I'm not sure how good we'd be
to do so as it would likely involve repackaging straight from RHEL
sources via a RHEL machine.

Anyway, happy to help in any way I can on this, I'm in our
SIG/Virtualization channel on Mattermost if anyone wants to get to me
easily.

Hi Hayden

If you can do this - the word awesome would be an understatement ;-)

I have been using oVirt for 7 years now and it is a fantastic product (I 
started using it when it was 3.1 or 3.4). I am in a similar position as Jason 
who started this thread. The main goal of my experiment described above is to 
see if I can deploy it on bare metal nodes with Rocky as a hypervisor 
replacement for CentOS. I actually wanted to convert to Proxmox but wanted to 
give oVirt one more chance :)

Thank you.

Kind regards,
Branimir


Thanks, Branimir.

I am really hoping that Sandro and the rest of the oVirt team can help 
make this possible for Rocky Linux.  It seems like it won't be too 
tricky.  I've heard offline from a lot of people who would be very 
interested in using Rocky Linux for this very purpose, so there's a lot 
of interest out there.  It would be a huge win for oVirt.

[ovirt-users] passing data between guacamole and xrdp server

2021-07-10 Thread Jason Keltz

Hi.

I have a custom use case where I would like to have two guacamole RDP 
connections that point to the same host, but the underlying xrdp start 
script would initialize one connection slightly different than the 
other.  I don't see a simple way that I can pass anything between 
Guacamole and the xrdp server which would allow the script to determine 
which connection the user chose in guac?  I thought *maybe* "client 
name" under "Basic Settings" but it seems to apply to Windows only.  It 
would be neat to be able to pass environment variables in.


Thanks,

Jason.

Looking in Rocky packages, this is not available yet:

To replace Centos as the production OS for oVirt, the community must also
rebuild advanced virtualization.

You can try to use Rocky and pull in the advanced-virtualization repo from
Centos as a temporary solution.


Ugh. Thanks for letting me know.  That's a *BIG* fly in the ointment 
right there.  I noticed that Alma doesn't do it either. In fact, I don't 
even see it in the Oracle Linux repository even though it must be there 
somewhere because I know they have their own 'RHEV' clone.


I would prefer to stay away from CentOS Stream for the virtualization 
platform.   The RHEL product itself would be a perfect solution, but 
it's rather costly if just using it for a virtualization host OS, and 
there are surprisingly no education discounts.  I have to see if Rocky 
will eventually provide it, or see if I can get internal funding for RHEL.

Hi Neal,

I read that somewhere, but for the LIFE of me, I cannot find the

loaded but with a warning in dmesg:

[ovirt-users] upgrading to 4.4.6 with Rocky Linux 8

2021-06-30 Thread Jason Keltz

Hi..

I'm looking to migrate soon from CentOS 7.9 with oVirt 4.3.10 to Rocky 
Linux 8.4 with oVirt 4.4.6.  I'm working on my kickstart of my 
standalone engine in a VM at the moment.


So far, with minimal experience with Rocky Linux, after my kickstart, I 
was able to run "engine-setup", follow all the defaults and then access 
my "new" engine via web.  I have to explore the actual procedure for 
installing on my current engine host, and restoring my data.


When oVirt team releases new releases, I'm just wondering if you test 
going from the last previous release (4.3.10 in this case) to each 
latest release?  I know that the documentation says we always need to 
make sure we update to each individaul major release, but I'm just 
wondering if this is something that oVirt team tests with each release? 
I'm very concerned for potential of failed upgrade, and the potential 
headaches that it could cause.


I see the 4.4.6 was released in time with RHEL 8.3.  I'd like to use 
Rocky Linux 8.4 because I believe RHEL has re-enabled mptsas (though I 
know still unsupported) from 8.4+ which will make things easier.


Any additional suggestions or caveats of the upgrade?

Thanks for any feedback,

Jason.

[ovirt-users] ovirt AD issue

2021-02-04 Thread Jason Keltz
A while back, I had reconfigured my oVirt engine to auth based on my 
Samba AD server, and everything was working perfectly fine. oVirt 
version 4.3.10.4-1.


Today, I tried to login with my account into engine and I see:

server_error: The connection reader was unable to successfully complete 
TLS negotiation: 
SSLHandshakeException(sun.security.validator.ValidatorException: No 
trusted certificate found), ldapSDKVersion=4.0.7, 
revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58


I recently added a secondary domain controller with Samba, and I realize 
now that there is an error.  Since I didn't pre-initialize samba with a 
TLS certificate, it generated a new CA, and certificate and key for the 
second server.  Since I'm not using the same CA as the first server, 
ovirt engine (which only has the CA of the first server) won't be able 
to talk to the second server... no problem I will fix that eventually.


However, when I re-ran "ovirt-engine-extension-aaa-ldap-setup", and 
followed the exact steps I did before, ovirt is connecting to the first 
server, failing with the above error, then connecting to the second 
server, and the same error.  The CA hasn't changed for the first server, 
nor has the certificate/key.  I verified that the CA certificate that I 
am giving ovirt is matching with the exact CA certificate of the first 
server.


How can I debug further?

[ovirt-users] errors upgrading ovirt 4.3.1 to 4.3.2

2019-04-05 Thread Jason Keltz

Hi.

I have a few issues after a recent upgrade from 4.3.1 to 4.3.2:

1) Power management is no longer working.  I'm using Dell drac7. This 
has always worked previously.  When I click on the "Test" button, I get: 
"Testing in progress.  It will take a few seconds. Please wait" but then 
it just sits there and never returns.


2) After rekickstarting one of my hosts, when I click on it, and choose 
"Host Console",  I get "Authentication failed: invalid-hostkey".  If I 
click "Try again", I'm taken to a page with "404 - Page not found Click 
here to continue".  The page not found is likely a bug.  Now, if I visit 
cockpit directly on the host via its own URL, it works just fine.  Given 
that I deleted the host and re-added to engine, it's really not clear to 
me how to tell engine to refresh.  I figured after rekickstarting the 
host, the problem would surely go away, but it did not.


3) From time to time, I am seeing the following error appear in engine: 
"Uncaught exception occurred. Please try reloading the page. Details: 
(TypeError): oab (...) is null Please have your administrator check the 
UI logs".  Another bug ...


Engine is standalone engine, not hosted.

Jason.

[ovirt-users] missing firewalld services on ovirt engine

2019-03-11 Thread Jason Keltz

Hi.

I've just converted my standalone ovirt engine from iptables to 
firewalld.  The configuration of the internal zone includes:



  
  
  
  
  
  
  
  
  
  
  


I'm wondering why the ovirt ports for , 6100, 7410, and 54323 etc. 
aren't encapsulated in a service file installed by ovirt?  Is this 
because I had initially installed iptables?  I suspect the answer is no 
because on my ovirt hosts (which I also converted to firewalld), I was 
able to find all the proper service files:



 
  
  
  
  
  
  
  
  
I'm also wondering whether ovirt will tell me if I go to upgrade any 
additional ports that need to be added for additional services?


Thanks!

One interesting point to add ---  For one server running CentOS 6 and 2

Hi,
well, we keep the date and who did that, but we can’t really keep all 
the logs forever. Well, you can if you archive them somewhere, but I 
guess that’s impractical for such a long time:-D


I wasn't really thinking in terms of logs.  I was thinking a database 
field that tracks the ovirt version that created the VM.




 VM Device subtab: (no Cirrus)



so this is a screenshot from VM where the button is grayed out when 
you start it?

Hm..it doesn’t look wrong.


Yes.


And then - if possible - describe some history of what happened. When was the 
VM created, when was cluster updated, when the system was upgraded and to what 
versions.
All I know is that everything was working fine, then I updated to 
4.2, updated cluster version, and then most of my consoles were not

upgrade or not.  I suspect it was most and not all VMs since some of 
them had been created later than 3.6, and this was  an older one.  I 
only have this one VM left in this state because I had deleted the 
other VMs and recreated them one at a time...
I will wait to see if you want me to try Vineet's solution of making

Thanks.
Can you get engine.log and vdsm log when you attempt to start that VM

Sure.. I restarted the VM (called "rs").

Console was available, and all hardware came back fine.

... but I won't try that yet in case you need additional information 
from the VM first.

Re: [ovirt-users] Console button greyed out (4.2)

Hi,

We upgraded one of our infrastructures to 4.2.0 recently and since 
then some of our machines have the "Console" button greyed-out in the

I changed their compatibility to 4.2 but with no luck, as they're 
still disabled.


Is there a way to know why is that, and how to solve it?

I'm attaching a screenshot.


Hi Nicolas.
I had the same problem with most of my VMs after the upgrade from 4.1 to 
4.2.

See bugzilla here: https://bugzilla.redhat.com/show_bug.cgi?id=1528868
(which admittedly was a mesh of a bunch of different issues that occurred)
Red Hat was never really able to figure out why, and I think they pretty 
much just dropped the issue because it seemed like it only happened for 
me.  In order to resolve it, I had to delete the VMs (not the disk of 
course), and recreate them, and then I got the console option back.
It's "good" to see that it's not just me that had this problem. There's 
a bug to be found there somewhere!!

Can you specify what did you upgrade, and in which order? Engine, hosts?
Cluster level, etc.?



I was running 4.1.8 everywhere. I upgraded engine (standalone) to 4.2,  
then the 4 hosts. I stopped ovirt-engine, added the new repo for 4.2,  
ran the yum update of ovirt setup, ran engine-setup and that process  
worked flawlessly. No errors. I had just upgraded to 4.1.8 a few days  
ago, so all my ovirt infrastructure was running latest ovirt and I  
also upgraded engine and hosts to latest CentOS and latest kernel with  
the last 4.1.8 update.  I then upgraded cluster level. All the VMs  
were going to be upgraded as they were rebooted, and since it's the  
reboot that breaks console, and since a reinstall brings it back, I'm  
going to assume it's the switch from 4.1 to 4.2 cluster that breaks  
it.  If I submit this as a bug then what log/logs would I submit?







Initially, after upgrade to 4.2, the status of many of my hosts changed
from "server" to "desktop".  That's okay - I can change them back.




You mean the VM type?


Yes.  VM type. Most of the VMs switched from desktop to server after  
the update.



My first VM, "archive", I had the ability to access console after the
upgrade.  I rebooted archive, and I lost the ability (option is grayed
out).  The VM boots, but I need access to the console.

My second VM is called "dist".That one, ovirt says is running, but I
can't access it, can't ping it, and there's no console either, so I
literally can't get to it. I can reboot it, and shut it down, but it would
be helpful to be able to access it.   What to do?

I reinstalled "dist" because I needed the VM to be accessible on the

network.  I was going to try detatching the disk from the existing dist
server, and attaching it to a new dist VM, but I ended up inadvertently
deleting the disk image.  I can't believe that under "storage" you can't
detatch a disk from a VM - you can only delete the disk.

After reinstalling dist, I got back console, and network access!  I tried
rebooting it several times, and console remains... so the loss of console
has something to do with switching from a 4.1 VM to 4.2.

I've very afraid to reboot my engine because it seems like when I reboot

hosts, I lose access to console.

I rebooted one more VM for which I had console access, and again, I've

lost it (at least network access remains). Now that this situation is
repeatable, I'm going one of the ovirt gurus can send me the magical DB
command to fix it.Probably not a solution to reinstall my 37 VMs from
kickstart.. that would be a headache.

In addition, when I try to check for "host updates", I get an error that

it can't check for host updates.  I ran a yum update on the hosts (after
upgrading repo to 4.2 and doing a yum update) and all I'm looking for it to
do is clear status, but it doesn't seem to work.

Re: [ovirt-users] Ovirt causing strange network issues?

2017-10-03 Thread Jason Keltz

Derek,
Have you used tcpdump to check what network traffic is coming out of your 
box? Is it possible that it is some kind of DoS attack from outside in or 
that your VM was compromised and is attacking other external hosts?


Hope you get to the bottom of it!

Hi,

I'm at my wits end so I'm tossing this here in the hopes that SOMEONE
will be able to help me.

tl;dr: Ovirt is doing something on my network that is causing my fiber
modem to go from 3-5ms to 300-1000+ms round trip times.  I know it's
ovirt because when I unplug ovirt from my network the issue goes away;
when I plug it back in, the issue recurs.

Long version:

I've been running Ovirt 4.0.6 happily on CentOS 7.3 for several months
on a single host machine. Indeed, the host had an uptime of 200+ days
and was working great until approximately midnight, September 21/22
(just over a week ago).  I was on an airplane halfway across the
Atlantic at that time, so it wasn't anything I did.

My network is configured as:

  fiber modem <-> edgerouter <-> switch <-> everything else

ovirt is living in the "everything else" area.

When I sit with a laptop connected to either the everything else range
or even directly connected to the fiber modem, I run 'mtr' and see
network times (starting at the fiber modem) that bounce all over the
place.  When I unplug ovirt I see consistent 3-5ms times.  Plug it back
in, voom, back up to badness.

I've spent several hours plugging and unplugging different devices
trying to isolate the issue.  The only "device" that has any effect is
my ovirt box.

I have tried to debug this in several ways, but really the only thing
that seems to have helped at all is shutting down all the VMs and the
hosted engine.  Once nothing else is running (but the host itself), only
then does the network seem to return to normal.

I'm really at my wits end on this; I have no idea what is causing this
or what might have changed to cause the issue right at that time.  I
also can't imagine what ovirt is doing over the network that could cause
the modem, two physical hops away, to lose its mind in this way.  But my
experiementation is definitely showing a direct correlation.

Help!!

Our storage guys do NOT think it's an XFS fragmentation
issue, but we'll be looking at it.


This is an interesting thread to read because the problem sounds quite 
similar:


http://oss.sgi.com/archives/xfs/2016-03/msg00447.html

In particular, quoted from that:

XFS maintains the full extent list for an active inode in memory,
As it is, yes, the memory allocation problem is with the in-core
extent tree, and we've known about it for some time. The issue is
that as memory gets fragmented, the top level indirection array
grows too large to be allocated as a contiguous chunk. When this
happens really depends on memory load, uptime and the way the extent
tree is being modified.


So in my case, I have a bunch of big XFS disk images for virtual disks.  
As the files are big with many extents, keeping all that information in 
memory at the same time may be the culprit.   Having many extents per se 
isn't the problem, but having enough memory to be able to store all the 
information simultaneously may be. Possible solutions would be to 
increase the default extent size of the volume (which I'm not sure how 
to do), defragment the disk, and hence less extents, or potentially add 
more memory to the file server.  It has 64G.



Hmmm... almost sorry to hear that because that would be easy
to "fix"...



They continued on the 24th, then on the 26th... I think
there were a few "hangs" on those times that people
were complaining about, but we didn't catch the
problem. However, the errors hit big time yesterday at
14:27 PM... see here:

If you want any other logs, I'm happy to provide them. 
I just don't know exactly what to provide.


Do you know if I can run the XFS defrag command live?
Rather than on a disk by disk, I'd rather just do it on
the whole filesystem.  There really aren't that many
files since it's just ovirt disk images.  However, I
don't understand the implications to running VMs.  I
wouldn't want to do anything to create more downtime.


Should be enough to copy the disks to make them less
fragmented.

Yes, but this requires downtime.. but there's plenty of
additional storage, so this would fix things well.



Live storage migration could be used.

I had upgraded the engine server + 4 virtualization hosts

them from CentOS 7.3 to CentOS 7.4.  virtfs, the NFS file

from 4.1.1 to current on September 20 along with upgrading
them from CentOS 7.3 to CentOS 7.4.  virtfs, the NFS file
server, was running CentOS 7.3 and kernel
vmlinuz-3.10.0-514.16.1.el7.x86_64. Only yesterday, did I
upgrade it to CentOS 7.4 and hence kernel
vmlinuz-3.10.0-693.2.2.el7.x86_64.

I believe the problem is fully XFS related, and not ovirt at
all.   Although, I must admit, ovirt didn't help either. When
I rebooted the file server, the iso and export domains were
immediately active, but the data domain took quite a long
time.  I kept trying to activate it, and it couldn't do it. 
I couldn't make a host an SPM.  I found that the data domain

directory on the virtualization host was a "stale NFS file
handle".  I rebooted one of the virtualization hosts (virt1),
and tried to make it the SPM.  Again, it wouldn't work. 
Finally, I ended up turning everything into maintenance mode,
then activating just it, and I was able to make it the SPM. 
I was then able to bring everything up.  I would have

expected ovirt to handle the problem a little more
gracefully, and give me more information because I was
sweating thinking I had to restore all the VMs!


Stale NFS is on our todo list to handle. Quite challenging.

Thanks..



I didn't think when I chose XFS as the filesystem for my
virtualization NFS server that I would have to defragment the
filesystem manually.  This is like the old days of running
Norton SpeedDisk to defrag my 386...

[ovirt-users] xfs fragmentation problem caused data domain to hang

2017-10-01 Thread Jason Keltz

Hi.

For my data domain, I have one NFS server with a large RAID filesystem (9 TB).
I'm only using 2 TB of that at the moment. Today, my NFS server  hung with
the following error:


xfs: possible memory allocation deadlock in kmem_alloc


All 4 virtualization hosts of course had problems since there was no
longer any storage.

In the end, it seems like the problem is related to XFS fragmentation...

I read this great blog here:

https://blog.codecentric.de/en/2017/04/xfs-possible-memory-allocation-deadlock-kmem_alloc/

In short, I tried this:

# xfs_db -r -c "frag -f" /dev/sdb1
actual 4314253, ideal 43107, fragmentation factor 99.00%

Apparently the fragmentation factor doesn't mean much, but the fact that
"actual" number of extents is considerably higher than "ideal" extents seems 
that it
may be the problem.

I saw that many of my virtual disks that are written to a lot have, of course,
a lot of extents...

For example, on our main web server disk image, there were 247,597
extents alone!  I took the web server down, and ran the XFS defrag
command on the disk...

# xfs_fsr -v 9a634692-1302-471f-a92e-c978b2b67fd0
9a634692-1302-471f-a92e-c978b2b67fd0
extents before:247597 after:429 DONE 9a634692-1302-471f-a92e-c978b2b67fd0

247,597 before and 429 after!  WOW!

Are virtual disks a problem with XFS?  Why isn't this memory allocation
deadlock issue more prevalent.  I do see this article mentioned on many
web posts.  I don't specifically see any recommendation to *not* use
XFS for the data domain though.

I was running CentOS 7.3 on the file server, but before rebooting the server,
I upgraded to the latest kernel and CentOS 7.4 in the hopes that if there
was a kernel issue, that this would solve it.

I took a few virtual systems down, and ran the defrag on the disks.  However,
with over 30 virtual systems, I don't really want to do this individually.
I was wondering if I could run xfs_fsr on all the disks LIVE?  It says in the
manual that you can run it live, but I can't see how this would be good when
a system is using that disk, and I don't want to deal with major
corruption across the board. Any thoughts?

Thanks,

Jason.

[ovirt-users] unhappiness with ovirt engine after upgrading file server handling storage domain

2017-05-10 Thread Jason Keltz

Hi.

I recently upgraded my oVirt infrastructure to the latest 
4.1.1.8-1.el7.centos, which went smoothly.  Thanks oVirt team! This 
morning, I upgraded my NFS file server which manages the storage 
domain.  I stopped ovirt engine, did a yum update to bring the server 
from its older CentOS 7.2 release to CentOS 7.3, rebooted it, then 
restarted engine.   At that point, engine was unhappy because our 4 
virtualization hosts had a total of 30 VMs all waiting to reconnect to 
storage.  The status of all the VMs went to unknown in engine.  It took 
almost 2 hours before everything was completely normal again.  It seems 
that the hosts were available long before engine updated status.  I'm 
assuming it's better to restart engine when I know that NFS has resumed 
on all the 30 virtalized hosts.  However, it's hard to know when that's 
happened, without trying to connect manually to all the hosts.  Is there 
a way to warn engine that you're about to mess with the storage domain, 
and you don't want it to do anything drastic? Sort of like a 
"maintenance mode" for storage?I would hate for it to start trying 
to power off hosts via power management or migrate hosts when it just 
needs to wait a bit...


Thanks!

Jason.

Re: [ovirt-users] several ovirt questions - CPU allocation, and use threads as CPU

Hi Jason,


How do I go about seeing how many CPUs I've allocated across all the VMs on a

  VMs that reqiure dedicated CPUs?

Unfortunately the UI is lacking in this area. We do not currently have
any overview page.

I will submit an RFE when I get a chance.


Also we do not currently support dedicated CPU to VM mapping. You can
use CPU pinning to select the CPUs that should be used, but the CPU
can be used for any other VM too (so it is a limitation for the VM
assignment, not for the CPU assignment).

There might be a workaround for this using the isolcpus
(http://www.linuxtopia.org/online_books/linux_kernel/kernel_configuration/re46.html)
kernel boot option and then puting VMs on those CPUs using pinning.
But we have never tested this.

Ok.

What happens if I allocate more cores than what I actually have?

We won't allow your VM to start if it requires more cores than
physically available on the destination host.

Actually, I think I wasn't clear with my message.  If I have only 4 
cores total, and I try to allocate 5 cores to one VM, I would expect the 
VM wouldn't start.  What I want to understand is what happens when I try 
to run 3 x 4 core VMs on a 4 core system.  By default, they would all 
share the 4 cores?  oVirt would never tell me that I am out of capacity 
as long as the VMs that I'm running are all under the total number of 
cores in the system?



If I specify say, a dual CPU system, would that system show up as 4 cores (2 
real cores and 2 hyper-threaded cores)

CPU pinning and core reporting always use thread IDs so it makes no
difference there.

But the scheduling takes this option into account when computing the
load or when checking if enough cores are available (useful with
relation to your previous question).
You didn't mention whether I'm at an advantage to enable "Use Threads as 
CPUs" or to leave it off?


Would you care to open a bug about the CPU pinning overview? It might
be a nice RFE considering we have something similar for NUMA already.

Sure!

Thanks!

Hello and sorry for dropping in so late.

The issue is that 3.5 engine created RNG device without sending the
device key (which should've been 'rng' but it wasn't properly
documented in the API as fixed in [1]). This caused the
getUnderlyingRngDevice method to fail matching the device (fixed in
[2]) and it would therefore be treated as unknown device (where the
notion of 'source' isn't known). 3.6 engine should handle it correctly
[3].

The implication is that when VM is created in 3.5 environment and
moved to 3.6 environment, the matching will work but there will be 2
RNG devices for the single one. Same goes for migration.

I'm not sure about the fix yet, to rescue the 3.6 VM we would have to
remove the duplicate device without specParams (meaning that address
would be lost) or remove the original device but adding it's
specParams to the new device. A temporary fix would be creating a hook
that does this.

I don't necessarily see this device listed in the host passtshrough.
In addition, since I'm able to connect to the serial device right now on 
the host, this would mean that I need to "blacklist" that device from 
the host so that when it boots, it doesn't load the driver?

[ovirt-users] upgrade from 3.5 to 3.6 causing problems with migration

2015-11-06 Thread Jason Keltz

Hi.

Last night, I upgraded my engine from 3.5 to 3.6.  That went flawlessly.
Today, I'm trying to upgrade the vdsm on the hosts from 3.5 to 3.6 
(along with applying other RHEL7.1 updates)  However, when I'm trying to 
put each host into maintenance mode, and migrations start to occur, they 
all seem to FAIL now!  Even worse, when they fail, it leaves the hosts 
DOWN!  If there's a failure, I'd expect the host to simply abort the 
migration  Any help in debugging this would be VERY much appreciated!

Hi.

I notice that the IP Address and FQDN fields for all of my VMs (mostly 
CentOS 6) in engine are empty.   This doesn't seem to affect any 
operation.   Why would this be?

[ovirt-users] Question about upgrading ovirt 3.5.3 to 3.5.4

2015-09-09 Thread Jason Keltz

Hi.

I have a system consisting of an engine + several hosts running 3.5.3, 
and I want to upgrade everything to 3.5.4.   According to the release 
notes, all I should do is:



# yum update "ovirt-engine-setup*"
# engine-setup


I did this with engine, and it seemed to upgrade okay.

I'm puzzled whether this applies to the hosts as well?  The release 
notes aren't clear to me in that respect.


Thanks for any assistance!

At host you can run "yum update" or "yum update vdsm" if you like to update 
specific.

Thanks!  The maintainer of the release notes should probably clarify 
this point in the notes.  Now I know! :)

Sorry Alon..

I'm puzzled.  I setup RHEL IPA server to act as an authentication
front-end for my ovirt installation.  It also acts as an IPA server for
all the servers involved in my ovirt installation.

I enabled my engine installation to authenticate with my IPA server like
this:

engine# engine-manage-domains  add --domain=EECS.YORKU.CA --provider=ipa
--user=ovirtadmin

Your new system refers to only LDAP, and not Kerberos, other than saying
that it obsoletes the legacy Kerberos/LDAP implementation.   Will
Kerberos support now be obsolete?  Since I've already invested the time
to get engine working with IPA and Kerberos, I don't really see the
point in changing things now, but I'd also rather deal with this now,
rather than down the line when I want to upgrade and find that my
existing installation is no longer compatible.Sooo -- does this
change still affect my current installation? Should I migrate? What do I
migrate to? and How?

Not at all.

The IPA provides several services, at least LDAP, DNS, Kerberos:

These two are not actually related and used for two different purposes:

1. LDAP - a protocol to access a repository (database) holding entity 
information.

2. DNS - a protocol to locate resources within network.

3. Kerberos - single sign on infrastructure, enables to create trust between 
entities and single server, while after successful authentication, entity can 
access other entities without presenting credentials.

Why do we use LDAP? LDAP is standard [simple(?)] protocol to acquire entity 
information.

Why do we use Kerberos? Mainly for users will not require to enter their 
passwords over and over to access services (SSO), and to not expose their 
credentials to services.

For various of incorrect reasons the legacy LDAP provider implementation used 
Kerberos to authenticate between the engine machine and the LDAP server. This 
actually breaks one of the major kerberos principals - do not expose the 
credentials to service. In our case the engine machine is the service and the 
user and password are sent to the engine machine so it can issue Kerberos 
ticket instead of it accepting restricted ticket from the user.

Moreover, using two protocols in order to perform authentication and 
authorization introduces complexity, performance impact and probably depend on 
one other service DNS srvrecord. So we need true services to be configured 
correctly and operating in order to be able to perform a task that can be 
performed using LDAP only.

In practice, if a service has access to user credentials (user/password) it can 
communicate directly using LDAP to the entity repository to very if these 
correct. This is similar to how Kerberos behaves in IPA environment, as 
password is actually stored in the repository.

The new implementation does exactly that, it uses only LDAP protocol to perform

 Subject: problems with power management using idrac7 on r620

 Hi.

 I've been having problem with power management using iDRAC 7 EXPRESS on
 a Dell R620.  This uses a shared LOM as opposed to Enterprise that has a
 dedicated one.   Every now and then, idrac simply stops responding to
 ping, so it can't respond to status commands from the proxy.  If I send
 a reboot with ipmitool mc reset cold command, the idrac reboots and
 comes back, but after the problem has occurred, even after a reboot, it
 responds to ping, but drops 80+% of packets.  The only way I can solve
 the problem is to physically restart the server.This isn't just
 happening on  one R620 - it's happening on all of my ovirt hosts.  I
 highly suspect it has to do with a memory leak, and being monitored by
 engine causes the problem.I had applied a recent firmware upgrade
 that was supposed to solve this kind of problem, but it doesn't.  In
 other to provide Dell with more details, can someone tell me how often
 each host is being queried for status?  I can't seem to find that info.
 The idrac on my file server doesn't seem to exhibit the same problem,
 and I suspect that is because it isn't being queried.

 Hi,

 fence agent for IPMI is based on ipmitool. So if ping/ipmitool is not
 working there is not much to do about it. I don't know enough about oVirt
 engine but there is no real place where fence agent can memory leak because
 it does not run as daemon.

Hi Eli..
Thank you!
I checked and health check is not enabled So the problem causing the 
idrac to go away is not status monitoring from ovirt after all...Hmm... 
Makes me wonder if actually enabling it will prevent the problem from 
happening.

 Hi Marek.

 Actually its the idrac that I believe has the memory leak.  Dell wants to
 know how often ovirt is querying the idrac for status and whether the delay
 is configurable.

Well oVirt does not query the status automatically by default
There is a feature that enables that
http://www.ovirt.org/Features/PMHealthCheck
Basically this feature depends on 2 configuration values :

PMHealthCheckEnabled that shoul be true if the feature is enabled
PMHealthCheckIntervalInSec which is defaulted to 3600 Sec , so it is 
checked in that case once in an hour


So, first please check if this is enabled in your environment

engine-config -g PMHealthCheckEnabled

engine-config -g PMHealthCheckIntervalInSec

Other scenario when status is used is when host becomes non-responsive

In case that host become non responsive :

After a grace period that depends on the host load and if it is SPM or not 
a soft-fence attempt (vdsmd service restart) is issued
If the soft-fence attempt fails we will do a real fencing (if power 
management is configured correctly on the host and a proxy host is found)

We are sending a STOP command
We are sending by default 18 status command , one each 10 sec until we get 
'off' status from the agent

We are sending a START command
We are sending by default 18 status command , one each 10 sec until we get 
'on' status from the agent


Those depends on the following configuration variables :

FenceStopStatusRetries - default 18
FenceStopStatusDelayBetweenRetriesInSec - default 10
FenceStartStatusRetries - default 18
FenceStartStatusDelayBetweenRetriesInSec - default 10

This can be changed using the engine-config tool (requires restart to take 
affect)

each host is being queried for status?  I can't seem to find that info.  
The idrac on my file server doesn't seem to exhibit the same problem, 
and I suspect that is because it isn't being queried.


Thanks,

Jason.

Hi Juan,

If you're using ovirt  3.5.2, then you should try to include as 
options: privlvl=OPERATOR,lanplus=1,delay=10

If you're ovirt = 3.5.2, then you probably only need: lanplus=1

Under CentOS 7.0, and 3.5.2, the default worked because 3.5.2 was the 
first release to include the default options for idrac7, but when 
fence-agents was updated with CentOS 7.1 release, lanplus alone is no 
longer valid syntax.  lanplus=1 is.  A bug is reported to this effect.


I hope this helps!

Re: [ovirt-users] adding LINKDELAY to ovirtmgmt when vdsm configures it

Argh x 10.

I have 2 x Intel 10G ports on an Intel X540 adapter.  If I kickstart a 
brand new host, and configure em1 with LINKDELAY=10, the system boots, 
and gets an IP via DHCP.  If I then add the host through engine, vdsm 
reconfigures em1 and removes LINKDELAY.  Now, since the network adapter 
takes a little extra time to initialize, install fails.  If I add 
LINKDELAY=10 back manually to 
/etc/sysconfig/network-scripts/ifcfg-em1, VDSM will happily remove it on 
the next reboot.  If I modify 
/var/lib/vdsm/persistence/netconf/nets/ovirtmgmt, and insert: 
linkdelay:10, and reboot, vdsm fills it in for me as I'd expect, but 
it's too late - engine thinks the install already failed!  I can delete 
the failed install host, and re-do the install.  This time it will 
work, but then my instructions are messy... Install the host, let it 
fail, modify a file manually, re-install... clearly, not clear!!   
Finally, as a last attempt, I've tried to copy 
/var/lib/vdsm/persistence/netconf/nets and bonds to the host during 
kickstart, hoping that when vdsm initialized, it would see those files 
there, and I'd have all 4 networks configured already for me. The result 
is weird.  ovirtmgmt configured fine including LINKDELAY=10.The 
other ones did not.I suspect it's a bad idea to write directly to 
/var/lib/vdsm/persistence/netconf ... What I want to do doesn't seem 
like it should be too complicated...


Ideally, when you add a host through engine, you should be able to 
specify custom network parameters.  Likewise, when you add the other 
interfaces, you should be able to do the same.  Any ideas how to solve 
this problem?

[ovirt-users] status of ovirt 3.5.1 with centos 7.1

2015-04-23 Thread Jason Keltz

Hi.
I wanted to check on the status of ovirt 3.5.1 with CentOS 7.1.  I'm 
pretty sure the current 3.5.1 engine has problems with CentOS 7.1 (?), 
but not sure about vdsm?  I know that 3.5.2 will resolve issues with 
engine...
(I'm asking because I've kickstarted CentOS 7.1 as a host, and am having 
a few problems (eg. unable to talk to power management) and want to 
avoid debugging if it's already known to be broken... :)


Thanks!

The power management appears to be a bug between vdsm and the fence
agents.  Are you using fence_ipmilan?  It seems to not be seeing
options.

Otherwise, I'm running CentOS 7.1 + ovirt 3.5.1 on hosts okay.
engine as well?  I thought I'd read something about that not working 
here... and I think I remember reading a blurb in the release notes for 
3.5.2 about fixing compatibility with CentOS 7.1.



My work-around (quick-n-dirty hack until I have more time to look and
file an appropriate bug) for fence_ipmilan is the following script in
/usr/local/sbin (I just need the lanplus option, adjust as needed):


#!/bin/sh

cat -  /tmp/ipmi.$$
echo -e '\nlanplus=1'  /tmp/ipmi.$$
cat /tmp/ipmi.$$ | /usr/sbin/fence_ipmilan.real $@
rm -f /tmp/ipmi.$$


Yep .. It's for an idrac7... I need lanplus and a few other options as 
well (which are apprently integrated into 3.5.2)..   It was working 
perfectly with ovirt-node, but now that I've switched from node to using 
my own CentOS 7.1 install, the problem was introdued. It's not clear if 
the same problem would occur if I was running CentOS 7.  There were a 
lot of errors in the engine log.  I will look into more detail tomorrow.


Thanks Chris!

[ovirt-users] Windows 7 install problem

I believe I'm following the instructions for installing a Windows 7 test

I create the VM, then when I go to Run Once, select Atttach Floppy

[ovirt-users] benefit to spice-xpi plugin over native spice and remote-viewer

2015-04-06 Thread Jason Keltz

Hi.

I'm wondering if someone can explain the benefit to using the spice-xpi 
plugin to access a console versus using remote-viewer natively from 
the browser, specifically on a RHEL system?  In particular, if you have 
the virt-viewer package installed, and not spice-xpi, and you go to 
visit a console, then the client downloads the configuration file, 
/tmp/console.vv, and calls remote-viewer /tmp/console.vv.  On the 
other hand, if you have spice-xpi installed, it seems that the client 
doesn't need to download the configuration file first, but calls 
remote-viewer --spice-controller.  In both cases, it appears to me 
that the result is the same.  However, using spice-xpi, there seems to 
be an additional 4 seconds delay before I get to the console.  The time 
doesn't really matter.  I'm just wondering if there's a benefit to using 
spice-xpi?

Hi.

I have 3 nodes in one cluster and 1 VM running on node2.  I'm trying to

I'm unable to decipher engine.log to determine the cause of the

Any help would be appreciated.

Thank you!

Re: [ovirt-users] accessing SPICE console when host not on management network

2015-04-02 Thread Jason Keltz
You call all of that configuration for accessing consoles, easy? :) :)  
Engine should be able to set up the proxy automatically...   I haven't 
used squid, so I have to look in more detail at the configuration that 
you've provided.


I did find some other functionality which would have been much much 
(much!)  easier for me to use had it worked.  I was able to Edit each 
host, go to the Console tab, then click Override display address, 
and for display address enter the name of the node.  I did this for each 
of my 3 nodes.  In theory, this should solve the problem.  Now, when 
accessing the console via remote viewer, the file that is sent from the 
engine includes the external IP of the node, so everything should work, 
but it does not...

Here's what I see:

(remote-viewer:20327): remote-viewer-DEBUG: Couldn't load 
configuration: File is empty


(remote-viewer:20327): GSpice-WARNING **: Connection refused

(firefox:20235): Gtk-WARNING **: Unable to retrieve the file info for 
`file:///tmp/console.vv': Error stating file '/tmp/console.vv': No 
such file or directory


If I choose to save the file instead of opening it directly via remote 
viewer, it does contain the proper hostname.   I can't telnet to port 
5900 on the virt host though, which is odd.  I thought it might be 
because the hypervisor firewall restricted the access, so I temporarily 
cleared all the firewall rules on the one host.  That didn't work either.


If I could make this work, it would solve the problem for me.

Jason.

You have to configure Spice Proxy on oVirt Engine by `engine-config -s 
SpiceProxyDefault=someProxy`. Here is my solution:


root@host021:~ engine-config -a |grep SpiceProxyDefault
SpiceProxyDefault: http://10.25.2.21:3128/ version: general

You can use Proxy on your public IP if you don't like to use VPN, but 
remember to make sure that your machines are secured enough.

I'm trying to figure out the most reasonable method for me to
access the console on my ovirt installation.
Each node has ovirtmgmt, storage, and external network connectivity.
The standalone engine host has ovirtmgmt, and external network.
I connect to engine via the external network, right click on a VM
and try to access the console.  If I use the Remote Viewer
method, the connection fails.  This is because my client on the
external network doesn't have access to ovirtmgmt.
I can access the spice-html5 client, and that basically works,
though it's crashed more than once.  I suspect that Remote Viewer
will be more stable.
So my question is - what is the best way for me to connect to the
console from the external network?
Either, I have to start up my client on a machine that has an IP
on ovirtmgmt (eg. remote login to engine, and run firefox there?)
or I have to route external packets from my host to say, the
engine host, and run IP forwarding there? probably not too secure...
or I have to figure out a way to make ovirt use the external
network for display traffic... that would probably be best (?) but
I can't seem to figure out whether it's possible.
In particular since the external network is a VM network (it's
actually 2 x 1 G links bound via LACP), and not part of ovirt
infrastructure, it's not clear if I can use it for display and VM
external connectivity as well.

Any thoughts would be much appreciated.

[ovirt-users] virtual machine does not boot from its hard disk

2015-04-02 Thread Jason Keltz
I have kickstarted my first CentOS 6 host under ovirt.  When it boots, 
the VM tries to PXE boot again rather than going to the hard disk.


If I look under Boot Options in my VM, there's only:

  * First Device: Hard Disk
  * Second Device: [None]

If I  Enable boot menu then I can Hit F12 when the machine boots and 
select the disk.


I suspect this is a bug, or am I missing something?

In addition, can you configure which of the network interface does PXE 
boot? or ovirt will always try all of them until it finds one that 
works?  It would seem natural to me to have another column under 
Network Interfaces labelled PXE where you decide which of the 
interfaces have PXE enabled.

This is not the problem because I can hit F12, choose the disk, and the

I *had* set the machine to PXE boot before hard disk, but after undoing 
that, the configuration seems to have held.

[ovirt-users] Hosted Engine on oVirt Node Hypervisor

2015-03-22 Thread Jason Keltz
I'm setting up some new oVirt infrastructure, and wanted to give hosted 
engine a try.  I downloaded and installed the oVirt Node Hypervisor ISO 
(3.5-0.999.201502231653.el7.centos) on one of 3 nodes.  One of the 
options in the hypervisor menu is Hosted Engine.  This requires an 
Engine ISO/OVA URL for download.  The thing is - as far as I can tell, 
there is no download link for this ISO/OVA on the ovirt release web 
site.  I also can't find anything in the documentation that refers to it 
(or even this menu in the hypervisor). I did find this after some searching:


http://jenkins.ovirt.org/user/fabiand/my-views/view/Node/job/ovirt-appliance_engine-3.5_master_merged/oVirt-Engine-Appliance-CentOS-x86_64-7-20150319.424.ova

(Now replaced with a build from 0322).  I asked on the ovirt IRC channel 
and was told that this might work, but because of new functionality 
introduced recently that it also might not. If the feature is available 
in the node ISO, shouldn't there be an appropriate release of the hosted 
engine ISO/OVA that works hand in hand with the node that I've 
downloaded?   If it's not there because it isn't ready, isn't this 
functionality something that should be added to maybe a beta node 
release and tested before being released into the stable node hypervisor 
release?


I asked on the IRC channel whether it might be possible for me to 
kickstart my own engine from the node.  I ran into trouble with that as 
well.   On the installed node, I can only configure one network 
interface.  This is, of course, intended to enable ovirtmgmt for 
communication with engine which would take over and configure everything 
else for you.  Of course, when you don't yet have engine installed and 
need to get it, this leads to a chicken and egg problem.  To kickstart 
engine on node, I need an IP (from mgmt), an image (I guess it could 
come from the mgmt network), but then I also need access to the external 
network (on another NIC) to be able to install the appropriate ovirt yum 
repository, and download the engine!  If I installed my own node 
manually instead if using ISO, I guess I could configure the network, 
and make it work, but I'm trying to take advantage of the work that has 
already been put into node to make this all possible.


Anyway, I'm certainly interested in any feedback from users who have 
been able to make this work.  I guess I could kickstart one node as an 
engine, create the virtual image there, suck the ova down to the mgmt 
server, install node, then use node to re-suck down the hosted engine 
image, but it just seems like a lot of extra work.  Somehow I think it's 
intended to be a little more straightforward than that.

I don't have details on this, and hope others have.

It would be helpful if the documentation for oVirt had more information

Is the feature Local Authentication abandoned in 3.3?
If not, what should I do to use it?

Question is unclear.

What do you call Local Authentication, after setup can't you login
using
admin user?

Sorry for that.
I mean, use users in /etc/passwd to login.


I never knew this is was an option.

Or you mean something new that was planned somewhere?

I am against of using native authentication for applications, as it enables
more privileges that users should have.

The proper way to do that is to use directory services, such as LDAP and
integrate the nss of system and application to use that directory.

Regards,
Alon

I saw this from**http://www.ovirt.org/Features/Local_Authentication%E2%80%8E
So I thought it would be available now..

It seems that I have to use ldap now.


In future you will be able to write plugin for authentication and authorization 
to do whatever you like.

This is still work in progress as far as I can see[1].

While I think this is a great future addition, I really believe that the 
default oVirt installation should include some form of integrated basic 
authentication using the integrated DB!  I was really surprised to see 
this functionality missing.  With the integrated DB, I have no idea why 
the functionality isn't there.  I know - it's all about priorities.  
While LDAP is common, still - not everyone uses it!  If I was buying 
RHEV, the lack of the basic built in authentication would have been a 
show stopper for me.  Do I *really* need to use LDAP when I've got a 
total of about 4 people maintaining everything?  In fact, even if I 
*was* using LDAP, the virtualization infrastructure has enough of its 
own complexity that I'd rather separate it from LDAP - one less thing to 
go wrong.   If I was buying RHEV, the lack of basic authentication would 
have been a showstopper for me.

Hi,

This is about attempting to address the difficulty of finding the edit-action in
the Setup Host Network dialog, as documented in Bug 984737 - usability: 
webadmin
difficulty in assigning client ip, no gateway possible in bugzilla.
We have a suggestion from Eldan (see attached 
HostSetupNetworks-HoverPopUp.png)
which was described in the BZ (comment #3) and seemed acceptable by the reporter
(comment #4), however IIUC - one of the main pain points described in the BZ was
the fact that the user could not find the option to Edit the connection 
properties
since he was looking in the wrong place, and needed to hover on the correct 
place,
in order to find that option.
So although the idea is somewhat helpful, my concern is that this solution is 
not
enough (comment #5).

Another proposal from Malini (comment #6) is to add an actions drop-down menu 
in
the form of a small gear icon-button - see attached 
HostSetupNetworks-DropDownMenu.png.
This proposal addresses my concern, however I have a question about another 
concern
with this solution:
would the actions-drop-down menu-items panel be revealed appear upon click or 
upon
hover?

if it will be upon hover, it might seem weird/be conflicted/be somewhat 
confusing
with the hover functionality that reveals the logical-network details pop-up.
The suggestion from Lior did include redesigning the tooltip frame to 
include an Edit command, which is certainly more intuitive than a 
pencil.   That being said, I do agree that the gear solution which has 
been proposed is *more* intuitive and honestly more in line with what I 
was expecting.  I didn't complain about Lior's response even though it 
didn't completely address my issue because it came from a designer, and 
I realized, looking at my desktop, that configurable elements often *do 
not* have hints that they are configurable.



If this proposal is accepted (see my comments below about both
proposals), one solution might be to get rid of the network details
tooltip. Most people probably don't use MTU, and the rest is just
explaining the network role icons; so maybe not that useful.


if it will be upon click, it means that in order to edit a logical network, two
clicks will be required in order to get to the edit dialog, as opposed to one 
click
in the current state and in Eldan's suggestion.
maybe having two clicks in order to get to the edit dialog is acceptable, 
however
there may be some solutions for that:

one possible solution would be to combine both attached suggestions, i.e. the 
actions
within the hover pop-up, as well as the actions drop-down menu, however it 
means that
there will be some redundancy of the actions availability.

That sounds bad to me regardless of the other alternatives.


another possible solution is to keep only the gear + down-arrow icon (or maybe 
only
the down-arrow icon), without the actual drop-down menu there, just in order to 
indicate
that there are some options available in that area, and have Eldan's pop-up 
appear when
hovering on that icon (or even on the entire logical-network area, as happens 
today with
the current details pop-up)

thoughts?

I like the gear icon because it's noticeable and easily recognizable.
However, keep in mind that bonds should also have the same icon to keep
a consistent design. Now imagine a configuration with several bonds on
the left-hand-side and quite a few networks on the right-hand-side; I'm
no designer, but it could get cluttered with all those gear icons.

It MIGHT be preferable to use the other design (tooltip with action bar)
and risk the odd person not easily finding it (no disrespect intended,
Jason). I have no idea, however, if it's gonna be just the odd person or
most people. I'd love to hear others' opinions.
Having not used bridging/multiple VLANS prior to my experimentation with 
ovirt, it's always been the network interface itself that I have 
configured with IP/subnet/etc (eg. 
/etc/sysconfig/network-scripts/ifcfg-eth0).  Most of my machines 
(hundreds) have single network interfaces, and I've never needed to use 
bonding/bridging/etc which kept my network configuration very simple.  
After experimenting with oVirt, and doing my share of reading, I 
certainly understand the concept of logical networks and their 
configuration with oVirt, and yes, it all makes a lot of sense NOW 
(well, except for the fact that really when it comes down to it, the 
Linux configuration for anything but basic networking is, in my opinion, 
anything but intuitive.)  Nonetheless, please keep in mind that a 
concept which might be completely crystal clear to someone who uses it 
on a daily basis might be a little less intuitive to someone who is 
using it for the first time.  Fortunately, I've got *plenty* of patience. :)

[Users] VLANs and oVirt 3.1

2013-07-24 Thread Jason Keltz

I'm experimenting with VLANs in my oVirt test setup with 3.1.

My ovirtmgmt, and storage network are each on a basic switch with no VLANs.
On the other hand, my public network has several VLANs available to me.  
The network operations team created a trunk for me with 2 x 1 GbT ports, 
aggregated with LACP, and passed it on with all VLANs.
In oVirt, if I bind the two network interfaces, and, and assign one IP 
to the bind (mode 4) without specifying a VLAN, everything works fine 
(untagged VLANS are assigned ID 494 which is what I want).
On the other hand, if I specify VLAN 494 in the logical network setup 
(or any of the other VLANs), it fails.  I don't see any traffic.

Network operations says that all VLANs are passed on the trunk.

How can I debug?

1 Gb links on the building switch.  If I configure the two network

if I simply hard-code VLAN 494 in the logical network setup, it doesn't 
work - I get no network traffic. I'm told that the switch is setup

That sounds normal to me. Traffic coming in on the native untagged VLAN
wouldn't appear on the VLAN interface. I have a similar set up, and I've
assigned an unused VLAN as the native VLAN on the trunk, added the VLANs I
care about to the allowed VLANs list, and created the appropriate tagged
logical networks.


Thanks, Martin. I thought that the native VLAN would come through on the 
VLAN interface as well.  While this would explain why I couldn't get at 
VLAN 494, it wouldn't explain why I couldn't get at another of the VLANS 
on the same link -- still no traffic.  I do a tcpdump and see nothing (but 
the LACP stats show the link is up).

[Users] ovirt LACP/port aggregation fails to initialize on node boot

2013-07-18 Thread Jason Keltz
I'm experimenting with LACP/port aggregation on my public network 
interface in my oVirt test setup. My goal is to bind two 1G ports 
together.  Our network operations team configured two 1G switch ports 
appropriately, and I set up the bond between eth0 and eth1 on the node 
using the engine.  I can't configure the IP of the interface statically 
because then I don't get the option to set a gateway, which I need for 
our public network.  Using DHCP worked before enabling LACP (which 
acquires the gateway from the DHCP record).  After enabling LACP, when 
the node boots, it doesn't get an address. The node gets hostname 
localhost.  I have to login to the admin, hit F2, ifdown PublicNet 
ifup PublicNet, but then it works!  There's obviously some minor delay 
issue during node initialization, but there should be some way to tell 
it to wait a bit longer?

Happy to help (and yes it was hard to see...)


Actually, Mike -- two of my networks were private and didn't need a
gateway... but two are public, and need a gateway!  Unfortunately, the
interface seems to be missing that option!?  It lets you configure an
IP, and a subnet mask, but where's the option for specifying a gateway
if you're specifying static addresses... (my guess is that it picks up
the gateway if you're using DHCP).


multiple gateways?
something like this?
http://www.ovirt.org/Features/Multiple_Gateways


Yes.  Sort of -- simpler actually.
I have 4 network interfaces in each node.
My management network consists of a 1 Gbit switch connected to all  
the servers in our machine room.  Here, I don't need to specify a  
gateway since servers on this network talk to only each other.   
Actually, I'm surprised I can't rename ovirtmgmt to something else to  
generalize it as just a management network, but it's not a big deal,  
I guess.
My Storage network consists of a 1 Gbit switch now - 10 Gbit soon.   
Again, I don't need to specify a gateway here.
Finally, the last 2 NICs are connected to the external network - a  
building switch that another Department controls.  Here, I definately  
need to specify a gateway, but of course with the current setup, I  
can't.  I will either have to hard code the gateway for these  
connections, or use DHCP.
Since there is only one gateway for the external connectivity, all  
on the same VLAN, I don't think I need the more complicated iproute2  
setup here.  I prefer to stay away from that if I can...


I'm surprised this isn't a more common configuration.

Re: [Users] Unable to view console via SPICE method on EL6.

I'm running with theEL6 release of ovirt-engine:

After creating a virtual machine, I cannot view the console if protocol
is set to SPICE.  If the protocol is set to VNC, I can view the
console, but it's not very convenient since I have to load a separate
VNC viewer, and enter the IP and port of the engine, and a randomly
generated password each time. How does one make console work via SPICE?
Is this a known issue because RHEL6 wouldn't have all the updated
libraries of later a later Fedora release?


which client are you using?


Actually, I realize the problem now... my client was a Windows client.
The server is EL6, the VM is EL6.  I'll try with a Linux client later.
I'm sure it will work.  It's not clear whether SPICE will also require
entering a randomly generated password.  The problem is the randomly
generated password.  There's probably a way to fix that as well... I
just need to look more.  oVirt is terrific, but finding all the
information from a variety of sources and putting it all together can
be tricky .. but I like a challenge! :)


Actually, I had another thought after clicking send You know, I  
sit writing this email on a Chromium device where SPICE won't work,  
and neither will VNC (at least to my knowledge).  Even if I had access  
to VNC here, I still couldn't see the console because I'm not  
connected to the management network (without some fancy SSH  
tunneling).  It would sure be nice if there was a truly multiplatform  
way of handling the oVirt consoles, and having the viewer integrated  
so that as long as I can login to the engine, I can view, no matter  
where I am.  Dreaming? :) I don't think so - I just woke up! :)

[Users] NIC problem with ovirt node

2013-07-12 Thread Jason Keltz

I've just installed my first ovirt node using the 2.6.1 image.
I have 5 network interfaces in the machine .. ovirt sees them as:

em1, em2, em3, em4, and rename6!

That last one seems a little odd, but that's a different issue, I 
guess.  From dmesg..



[4.650156] systemd-udevd[213]: renamed network interface eth2 to em4
[4.656189] systemd-udevd[212]: renamed network interface eth0 to em3
[4.662193] systemd-udevd[209]: renamed network interface eth1 to em2
[4.670385] systemd-udevd[214]: Tried to rename network interface 
eth3, but the target name em2 already exists! The names that udev 
rules assign to network interfaces must be changed. Avoid names that 
collide with kernel created ones. A workaround will be attempted now, 
but this WILL BREAK in a future release! See 
https://bugs.freedesktop.org/show_bug.cgi?id=56929#c3
[4.675179] systemd-udevd[214]: renamed network interface eth3 to 
rename6


What IS a big deal is that every time I configure one network interface, 
the others go back to unconfigured.  I'm told this is because I should 
only configure one on the ovirt-node, and then use the engine to 
configure the rest.  Okay -- does it say that somewhere that I missed? 
:)   but when I'm in the engine, I can click on the node, and see that 
it's up.  I can click on network interfaces, and see that one is up, and 
the other are down.  I can create networks on the engine, and I can 
assign the nodes interfaces to those networks, but for the life of me, I 
can't figure out where I assign an IP to the nodes interfaces!!   
Surely, the place to do that would be under the Host tab, yet it 
doesn't seem to be there...


Any help would be much appreciated.

Host Tab - Network Interfaces - click on Setup Host Networks

On the popup, hover over the logical network (not the nic) and a
little pencil or pen (or some other graphic) that is used for
editing.  Click on that and you'll get another popup where you can
choose static/dhcp and set gateway, ip and netmask.


Thank you *so* much!  I did not see the little pencil!!!

[Users] adding biosdevname=0 to kernel grub line on ovirt-node persistent

2013-07-12 Thread Jason Keltz

Hi.

I'm wondering if it's possible to modify the kernel line (in my case, 
appending biosdevname=0) on an installed ovirt-node?  Adding it during 
boot works - I'd just like to know how to make the change persistent.


Thanks,

Jason.

[Users] RAID1 mirror on ovirt-node + engine nfs server

2013-07-06 Thread Jason Keltz

Hi.

I've been reading about ovirt, and ready to try my own experiments with 
it.  I have two small questions..


When an ovirt-node is installed from the standard ISO, there's no 
mention in the documentation about setting up a RAID1 mirror for the 
root disk on the node.  I'm sure that once I get around to working out 
kickstarting the node, I could easily install the raid1 mirror, but I'm 
just wondering why I don't see that in the default ISO. Maybe I'm just 
missing something.  Is redundancy of the disk on the node not 
important?  Sure, if the node goes down, I guess the VMs could be run on 
other nodes, but if we can prevent the node from going down in the first 
place, then why not?


I also have a question about the storage backend.  In particular, I have 
a pretty powerful server that I intend to use as the NFS server, and a 
few servers to use as nodes.  On the other hand, I don't have a powerful 
machine (at the moment) to use for the ovirt-engine.  Would it be poor 
practice to run the ovirt-engine ON the NFS server?  During engine 
setup, I see that you can setup an NFS share for ISOs from the 
ovirt-engine, but I don't think there's mention of just generalized 
storage there.  I suspect it's poor practice, but I thought I'd ask 
anyway.   My setup will be relatively small (say, 4 nodes), and this 
would let me reduce 1 general server from the infrastructure (dedicated 
ovirt-engine).


Thanks! :)

Jason.
