Their user guideline is probably based on UI for the masses. I'd argue
that oVirt, particularly the admin portal, is for a much more
technical audience. I think right-click should stay for admin portal.

Users are more likely to be less technical. I'd care much less if
everything in the user portal had its own button or was in a menu list.

Unless you've set up the engine as a proxy, wherever you're connecting from
must be able to reach the network that the hosts are on.

When I ran into this, I set my browser to save the .vv files instead of
running the remote-viewer client directly, and then I could look at the
contents of the .vv file to see which IP address it was trying to connect
to. I ended up creating a VPN tunnel from my laptop to a gateway machine
that could reach my internal ovirtmgmt network.

I think the 'confirm node reboot' step can be stepped if you put it into
maintenance before rebooting. I think it's needed when a host which was
running VMs gets hung and you need to force a reboot. Confirming the reboot
lets the engine know that those VMs are no longer running on that node. But
it certainly won't do any harm to do it anyways.

I just tried to repeat the experiment, and of course it worked fine.

One bug that I found that seemed to be similar was

I had this issue too, except I had 100% cpu usage reported on the web

Since I upgrade to 4.0, I get this annoying message when I try to log in
again after I've been away for a while. On 3.6 the ui would go to a login
screen after some period of inactivity, and I could log right back in. With
4.0, logging in after inactivity goes to a page with this message, and I
have to click to get a login page and then log in again. This is very
annoying. Is there a way to revert to the old behavior?

So it turns out that it wasn't the cluster compatibility that I missed, but
that the data center compatibility level needed to be updated to 3.6 as
well. I just didn't read the error message closely enough.

For the record, I ended up using 'yum history' to roll back the updated

I think you need to enable CentOS Virt SIG repo to get the latest qemu-kvm:

# yum install centos-release-qemu-ev

qemu-kvm-common.x86_64   10:1.5.3-126.el7 base
qemu-kvm-common-ev.x86_6410:2.6.0-27.1.el7centos-qemu-ev

There was an existing bug. Unfortunately it's another case of people just

'get over it'.

It is a little distressing that it fails with no indication of why it's
failing. It would be nice if something caught stderr to be able to log it.


I also forgot about my 3rd issue - the GUI 'broke' because I had a CNAME
for ovirt.local to ovirt-engine.local. Luckily I don't have a lot of users
to retrain to use a different domain name.

[ovirt-users] recovering from failed 3.6 -> 4.0 engine upgrade

2016-12-23 Thread Robert Story
Hello,

I'm trying to upgrade to 4.0 from 3.6. I dutify checked that my clusters
were set to 3.6 compatibility and started the engine upgrade. unfortunately
I forgot to check the unused Default cluser. :-/

So the upgrade failed, but the 4.0 rpms were installed, so the engine won't
start. How can I fix the compat level (or delete Default cluster)?

I found this message
 that suggests
that the engine should be startable if only the update rpms were installed,
but part of the install procedure updates all the rpms, including the
engine.

I created this bug:

  https://bugzilla.redhat.com/show_bug.cgi?id=1408493


Any help on how to proceed appreciated, either here or on IRC..

It's pretty much instantaneous since it's the same file system. Saves the

I'd guess that it's a misunderstanding of what kvmclock is. Someone
guessing based on the name might think that it keeps the vm time in sync
with the host. Which might lead one to think it would conflict with ntp
(two different things trying to manage time).

If you know that kvmclock is essentially just a way to monitor the passage
of time (tick-tock-tick-tock) using the host's timer, then it makes sense
that you need also need ntp to tweak the current time to adjust for the
minor drift inherit in any clock.

Thanks for that workaround. I've added it to the bugzilla. The easy manual
workaround I tried was:

# mkdir /rhev/data-center/mnt/ovirt-nfs.localdomain:_ovirt_hosted-engine

# /usr/bin/mount -t nfs -o soft,nosharecache,timeo=600,retrans=6,nfsvers=4 \
  ovirt-nfs.localdomain:/ovirt/hosted-engine \
  /rhev/data-center/mnt/ovirt-nfs.netsec:_ovirt_hosted-engine

which got the hosts operational again.

Thanks for all the help!

[ovirt-users] Failed to connect Host to the Storage Domains hosted_storage.

2016-07-22 Thread Robert Story
Hello,

I'm in the process of upgrading from 3.5.x to 3.6.x. My hosted engine and
hosts in the primary cluster are all upgraded and appear to be running fine.

I have a second cluster of 2 machines which are just regular hosts, without
the hosted-engine. Both have been marked non-operational, with the
following messages logged about every 5 minutes:


Failed to connect Host perses to Storage Pool Default

Host perses cannot access the Storage Domain(s) hosted_storage attached to the 
Data Center Default. Setting Host state to Non-Operational.

Host perses reports about one of the Active Storage Domains as Problematic.

Failed to connect Host perses to Storage Servers

Failed to connect Host perses to the Storage Domains hosted_storage.


I could see the normal storage/iso/export domains mounted on the host, and
the VMs running on the host are fine.

I shut down the VMs on one host, put it in maintenance mode, installed 3.6
repo and ran yum update. All went well, but when I activated the host, same
deal.

I've attached the engine log snippet for the activation attempt.

So more detail attached. The agent is sending:

Which the broker sees:

It then refreshes the local config file:

So after some debugging with Simone on irc, we've determined that the issue
is the agent timing out trying to communicate with the broker. The problem
is that we have no idea why.

So I tried to reinstall instead:

- host -> maintenance
- host removed from cluster
- yum remove ovirt\*
- yum install ovirt-hosted-engine-setup
- hosted-engine --deploy
  - chose new node id
  - reused same name/hostname

Once the host activated, it went right back to the same state.

I'm open to any suggestions to get me back on track. The engine is at
3.6.7, but functioning hosts are still at 3.5.x. Should I try to upgrade
the engine and a host to 4.0.x? I had planned on having a stable 3.6 system
for a few days before trying to jump to 4.0. Or is there some way to go
back to 3.5?

Re: [ovirt-users] direct mounting of vm disks?

2016-06-27 Thread Robert Story
So as (bad) luck would have it, I needed to restore an older backup that
the one I initially used. This time I decided to dig deeper into this
possibility, and got it working. libguestfs took care of all the dirty work,
even with dealing with snapshots and thin provisioning. Here's what I did:

- yum install libguestfs libguestfs-tools-c
- find the disk id
  - via GUI 'Disks' tab, search for VM in 'attached to' column, copy disk ID
- shut down vm
- on nfs server
  - switch to the directory for the ID found above
- e.g. cd /srv/ovirt/storage/*/images/$ID/
  - find latest modified file: ls -lt
  - mount it: guestmount -a $last_modified_file -m /dev/vg_el7/root /mnt/tmp
  - start restore
- cd /mnt/tmp
- ionice -c 3 tar xvf /tmp/backup.tar

Average load on my NFS server for about 12 VMs is generally less than 1.
During the initial restore over the weekend, run on the VM, restore took 5
hours and the load climbed up to 16. I'm running the new restore now, and
the load is holding steady at just under 2.

[ovirt-users] direct mounting of vm disks?

2016-06-25 Thread Robert Story
Hello,

I'm using oVirt 3.5.x w/nfs for vm file storage. I'm trying to restore a vm
from backup, which entails:

 - scp backup.tar to vm
 - untar backup on vm

this means all the data makes 3 trips over the network, each of which
causes a load spike on my nfs server. That nfs load, of course, affects all
other vms.

what I'd like to be able to do is

 - scp backup.tar to nfs server
 - stop vm
 - mount vm disks on nfs server
 - untar backup on nfs server (using ionice to minimze load impact)
 - unmount vm disks
 - start vm

I remember that I used to use kpartx to mount regular KVM disks, so I'm
hoping that it can also be done here. Anyone else tried to make this work?

I saw that too, and tried pings first. Those worked fine, and the

I'm going to reinstall and move a host from a different lab. We'll see if I

Hmmm..

  # engine-config -g VdsmSSLProtocol
  VdsmSSLProtocol: TLSv1 version: general

Looks like it's already set to TLS, making me wonder why I needed to remove

Luckily seeing SSL+java in the log tickled my memory about java disabling 
SSLv3, and google helped me find this workaround:

 - edit /usr/lib/jvm/java/jre/lib/security/java.security
 - look for jdk.tls.disabledAlgorithms
 - remove SSLv3 from the list
 - service ovirt-engine restart

Google also tells me that this should be an issue for 3.5, and there is a
vdsm setting, VdsmSSLProtocol, that can be set to use TLS, but I can't find
how to change/set it. Anyone know the secret?

So naturally it shows up again during a holiday. I came in today to find 1
of my 5 nodes (the SPM and host where hosted engine is running) with two
vdsmd threads chewing up 90-100% of the CPU. I applied the patch from above
and restarted vdsmd. This resulted in another node being selected as the
SPM, and within about 15 minutes, that node had the same issue. Applied the
patch to the new node, and restarted vdsmd, and the SPM went back to the
previous (now patched) node. Hopefully things will stay stable.

I've attached snippets of the logs from the SPM when the problem started,
along with the server/engine log snippets from the hosted engine around the
same time..

[ovirt-users] oVirt hosts and yum updates

2015-11-12 Thread Robert Story
I was wondering what other folks do to keep their oVirt hosts up to date,
both with the base OS pacakges and oVirt packages.Is it safe to enable
yum-cron? I'm concerned that it might cause issues if vdsm/ovirt packages
are updated without following the correct procedure, but would like other
OS packages to be kept up to date.

[ovirt-users] vdsm using 100% CPU, rapidly filling logs with _handle_event messages

2015-11-12 Thread Robert Story
I'm running oVirt 3.5.x with a hosted engine. This morning I noticed that 2
of my 5 hosts were showing 99-100% cpu usage. Logging in to them, vdsmd
seemed to be the culprit, and it was filling the log file with these
messages:

VM Channels Listener::DEBUG::2015-11-12
08:09:26,292::vmchannels::59::vds::(_handle_event) Received 0011. On fd

08:09:26,294::vmchannels::59::vds::(_handle_event) Received 0011. On fd 
removed by epoll.

I googled to see how to change the debug level to turn of DEBUG messages
for vdsm, which referred me to libvirtd.conf, but the debug level there was
not set, which should have meant a log level of 3 (warnings and errors), so
I'm not sure why the log was filling up with DEBUG/INFO messages.

I restarted vdsmd, which resulted in those nodes being marked as
'disconnected', but they did eventually recover and loads went back to
normal.

This may or may not be related to the fact that the 3 hosts where this did
not happen can't seem to keep their ha brokers up. I'll be starting a new
thread on that shortly.

[ovirt-users] _initialize_sanlock cannot get lock, host already holds lock on a different host id

2015-11-12 Thread Robert Story
I'm running oVirt 3.5.x with a hosted engine. On 3 of my 5 nodes,
ovirt-ha-agent won't start, complaining that "(_initialize_sanlock) cannot
get lock on host id 5: host already holds lock on a different host id."

Running 'grep host_id /etc/ovirt-hosted-engine/hosted-engine.conf' on each
host shows that they all have different unique ids, 1-5.

How can I debug this? Is there a command I can run to see which host holds a
sanlock for each id?

Just to clarify, this isn't about a vm. The engine VM is up and I'm not
having issues with any other vms. The problem is with the ovirt-ha-agent.

When I try and create an iso domain with the same NFS path as another
domain I get 'the selected storage path is not empty[...] Either remove the
existing Storage Domain from this path, or change the storage path.'

I had the same goal, but for multiple independent ovirt installs. My
work-around is to deal with it outside ovirt.

- create generic nfs export for my iso mirrors
- create iso export points for each install
- add iso mount to each install
- manually (or using puppet, etc) add mirror mount on each host node
- run a script that creates a symlink in each ovirt iso mirror for all the
  isos in the mirror export
  - 3.5 handles iso images in subdirectories, but 3.4 does not [1], so the
script creates symlinks for every iso image in the top level of the iso
export for 3.4, while only needing a symlnk to the distro directory fro
3.5.

It's a hack, but it works.


Robert

[1] 3.4 will descend to subdirectories to display the list of iso images
when attaching them in the UI, but the host will fail to boot because it
can't find the image unless it's at the top level.

Since I've upgraded, I figured I'd reproduce and send new logs. In that
process, I noticed that the ha-agent was down on 3 hosts, and the 2 other
hosts were the ones generating the messages. So I restarted ha-agent on all
5, disabled global maintenance for 2 minutes, re-enabeled it, then ran a
grep on all the logs on all 5 hosts for those 2 minutes. I'll sent that to
you directly, as it's rather large to be sending to the list..

All 3 hosts that had down ha-agents were down again, so I'm guessing
that's the issue..

As an experiment, I migrated the engine VM to one of the hosts with a
working ha-agent process, and I'm no longer getting getting these emails.

So the next question is: how can I fix the ha-agent on my other three
nodes. Seems to be an issue with host_id and sanlock...

It looks like the ha broker on the host currently running is having issues

engine vm running, and the complaining host...

[ovirt-users] Neutron Appliance questions

2015-07-28 Thread Robert Story
Hello,

I have an oVirt 3.5.x install on CentOS 7.1, and I'm trying to wrap my head
around how to use the Neutron appliance.

In the video demo, two hosts attach the neutron network to their eth1
interfaces, and their VMs can communicate with each other. But the demo
doesn't go on to show how to connect those VMs to the internet with
floating IPs.

In the OpenStack Neutron videos I've watched on youtube, the common basic
configuration seems to be a single 'network node' that connects to the
public and private networks and routes to the 'compute nodes', which aren't
connected to the public network. With the oVirt/Neutron integration, it
seems like all hosts are both 'network' and 'compute' nodes, meaning that
they need to be connected to the public network. Is that right, or am I
missing some fundamental concept? Is it possible to designate 1 or 2 hosts
of a cluster (with public network access) for the neutron appliance, while
the remaining hosts only have private network access + floating IPs for VMs?

[ovirt-users] how to prepare for an engine re-install

2015-02-18 Thread Robert Story
I'm running ovirt (engine 3.4.0-1.el6) on a dedicated engine machine with a
degraded raid array. This has caused the root filesystem to go read-only,
and the engine crashed. I can restart the engine, but after doing so, the
web page just loads a blank page. All nodes and VMs seem to be fine, I just
can't manage them via oVirt.

Because I'm offsite, my recovery option is likely limited to a reinstall of
the OS and ovirt.  I'm hoping for some pointers on what I can do in advance
to minimize the pain of this transition. 

- Am I going to be able to recover without having to shut down VMs,
  exporting and importing?

- what directories should I back up?

- when I reinstall, should I upgrade and install 3.5.1, or first install
  3.4, get it working, and then think about upgrading?

- Is it possible/recommended/crazy to migrate to a hosted engine instead
  of a dedicated machine?

So I want to prepare for the worst before I try a reboot. If I'm lucky, the
reboot will at least come up with a writable filesystem, and I won't need to
re-install. If it doesn't come up, I want to be as ready as possible for
the reinstall.

Any hints and/or tips appreciated..

(I'll also be hanging out in the irc channel if anyone wants to respond in
that venue..)

You will need to migrate existing KVM guests to oVirt. There is a tool,
virt-v2v, that can help with the conversion. Unfortunately it's a long,
slow multi-step process. Hopefully google can help find some documentation

[ovirt-users] how to 'reset' a failed install?

2014-11-07 Thread Robert Story
I've been doing lots of unsuccessful 3.5 hosted-engine installs in my lab,
where it's easy for me to re-install the OS if I need to start over. Now I
need to try an install in a remote datacenter where I won't be able to
re-install the OS. So I was wondering if there is a way to 'reset' a failed
install so that another install can be attempted...

My thoughts so far are:

- stop vdsm, supervdsm, and libvirt
- use etckeeper to reset everything under /etc
- delete old log files
- delete hosted_engine storage domain on storage (if install got that far)
- restart vdsm, supervdsm, and libvirt

What am I missing? Maybe some remnants in /var (hmm, probably the vdsm
persistent config)? Anything else?

Hmm.. When you say 'required network', I think 'required' in terms of the
oVirt gui. That wouldn't apply to my case, because ovirt hasn't been
installed yet. The underlying host has multiple networks, but nothing has
been configured in ovirt (unless the install detects and adds them).

[ovirt-users] 3.5 install issues: The VDSM host was found in a failed state

2014-10-26 Thread Robert Story
So I tried install #6 today on another machine. I dedicated eth0 to
ovirmgmt and put the default route and vlans on eth1. The install got to
the point of starting the VM the second time for the engine install (which
completed fine), but then:

[ INFO  ] Engine replied: DB Up!Welcome to Health Status!
  Enter the name of the cluster to which you want to add the host 
(Default) [Default]: 
[ INFO  ] Waiting for the host to become operational in the engine. This may 
take several minutes...
[ ERROR ] The VDSM host was found in a failed state. Please check engine and 
bootstrap installation logs.
[ ERROR ] Unable to add hosted_engine_1 to the manager
  Please shutdown the VM allowing the system to launch it as a 
monitored service.

I shut down the engine VM, but now it seems to be in a reboot loop,
starting and then being shutdown and rebooted, by the HA agent, I assume..

Logs for this install are at http://futz.org/users/tmp/ovirt6/. (The first
hosted-engine was aborted before it started to fix DNS for of engine VM,
but I included it for completeness).

[ovirt-users] 3.5 install issues: failed to setup ovirtmgmt

2014-10-25 Thread Robert Story
I'm on my 4th attempt to get a 3.5 hosted-engine set up on CentOS 6.5. I
seem to hit a different snag each time. The first 3 were with the ovirtmgmt

and see if I had better luck. But this install failed even earlier, when
creating the management bridge:

still no luck. that log is at

I've always thought it would be a good idea to have a 'storage agent' to
run on storage domains, which could perform some operations more optimally
that the current system. For example, exporting/importing domains currently
reads the whole VM image over the network, then writes it back. In my case,
my storage is all located on the smae NFS server, which could simply do an
OS copy locally, instead of reading/writing gigabytes over the network. I
don't know if other storage type could perform similar optimizations

[Users] taking advantage of extra disk space on nodes

2014-02-12 Thread Robert Story
So I've got a handful of oVirt nodes now, and most of them have over 100G of
unallocated disk space. I'm trying to figure out how to best take advantage
of that space. I see two possibilities: storage for oVirt, or
backup/archive storage.

I'm currently using a single NFS server for VM/iso/export storage (oVirt
3.3.x on CentOS, if it matters) and don't need to scale to hundreds of
nodes (probably 10-20, max). Is current gluster support stable enough for
production? What are the pros/cons of gluster vs NFS?  I like the idea of
not having a single point of failure but worry about performance.

The other option is to stick with my NFS server and use the extra storage
for archive/backup space. Here I'm looking for reliability (i.e. losing a
server won't cause data loss) over performance. Are there pros/cons to
gluster vs ceph? Will either/both peacefully co-exist with an ovirt node?

All suggestions welcomed. Thanks!

[Users] networking: basic vlan help

2014-01-23 Thread Robert Story
Hello again,

I'm new to VLANs and have a few questions. Right now I just have the mgmt
interface (bridged with eth0) on my all-in-one oVirt test setup. I want to
separate some VMs from the public facing net, which I think means that they
need to be on a different VLAN.  I created two new networks, pubX and
privY, with vlan ids X and Y, but couldn't assign them to eth0 because the
current mgmt network is non-VLAN. I was about to enable VLAN tagging on the
mgmt network, but I wanted to make sure that doing so wouldn't do anything
to eth0 that would disrupt access to it (I only have remote access and don't
want to lock myself out).  Also, if it is safe, does the mgmt vlan tag id
matter? is 0 the right value?

Any/all help, hints, tips or references to examples/links greatly

AM For an all-in-one, what I would suggest is the following procedure:

Excellent, I'll try that. Thanks!

My next question is for future planning. There is a second interface
(eth1) with a separate physical network which only contains the engine,
nodes and the nfs server.

 | internet |-|---|--|
 +--+ ++  +---+  +---+   eth0
  | engine |  | node1 |  | node2 |
+-+   ++  +---+  +---+   eth1
| nfs |---|---|--|
+-+

Can the mgmt network be easily moved to eth1? Then the pubX would be
non-vlan on eth0, and mgmt + privY would be on eth1. If all the eth1
interfaces are connected to a dedicated/isolated switch, does that switch
need to explicitly support vlans, or does it matter?

AM Sorry, privY on eth1.

For VM to VM communication that doesn't need to go over the public net..

[Users] another networking question: ssh to VM with private dhcp addr

2014-01-22 Thread Robert Story
Hello,

I've got oVirt 3.3.x all-in-one up and running on CentOS 6.3. The IP
address on the ovirtmgmt bridge is static/public. I have not done any
additional network/VLAN configuration.  If I create a VM and give it an
address on the same subnet, I can ssh to it just fine.

If I create a VM and let it use dhcp, it gets a 172.31.x.x address.
Outgoing access works fine, but I can't figure out what to do to allow me
to be able to ssh into those VMs.  With straight KVM the VM private network
was on a virtual interface on the host, making it easy. But I can't figure
out how to do it with oVirt.

Any help greatly appreciated. Thanks in advance.
