Well, I actually wanted to move the physical disk.  There was 2TB of data on 
it, and I didn’t want to move it via a GB network connection.  

I ended up doing it using basically the method I posted yesterday…I shutdown 
the old oVirt system, moved the disk to the new system.  Created a new data 
domain on the disk, then created new VMs and disks in the new data domain, 
after the new disk was created, I just moved it from the directory of the old 
data domain/VM into the new one and fired up the VM.

Instead of waiting hours and hours for 2TB of data to be copied, I moved my 4 
VMs in a few minutes.

A way to attach an existing on-disk VM image is really needed.

Re: [Users] vmware image conversion

[Blaster]

I have used this method successfully several times, but the problem is, 
this only converts the format of the image, it doesn't do any tweaks to 
the actual image needed to boot it in the new environment.  Windows for 
example, is likely to blue screen because it's not very good at 
detecting boot disk controller changes.


This is what the merge-ide script does, it relaxes the Windows checks on 
boot for new disk controllers.  Search for my post about how I converted 
my Windows guest from ESX to ovirt.

ESX is not the only platform that people run VMWare on.  I am trying

fine, but there is no migration path.  Other people may have VMs on

Re: [Users] vmware image conversion

[Blaster]

One of the issues I have with virt-v2v is that it requires an import 
storage domain on your ovirt server to import the image to, then you 
need to copy that image again into your vm datastore. Lots of data 
moving around slow gigabit networks.


oVirt still needs a way to easily add a vm disk image w/o having to go 
through the silly import method.

I can set the correct time, reboot, comes back up an hour behind.  I’ve tried

What am I doing wrong?

And what affect does setting the time zone in the properties supposed to have

[Users] unsupported configuration: spice secure channels set in XML configuration, but TLS port is not provided.

[Blaster]

Hello,

I’m using overt 3.3 on Fedora 19.

I had quite a bit of trouble getting everything up and running (All In One).   
My biggest problem was around vdsm, it crashed out during the interface 
configuration so I followed the instructions here  
http://www.ovirt.org/Installing_VDSM_from_rpm which had me disable TLS.  None 
of that ever worked, so I ended up creating the bridge myself, running 
engine-cleanup then engine-setup again.

Now when I run my VMs I get the following error:
unsupported configuration: spice secure channels set in XML configuration, but 
TLS port is not provided.

So something got messed up somewhere.

I can’t figure out where the XML files for each VM are stored.  

How can I resolve this error?  Google searches haven’t turned up anyone having 
this problem.

Thanks for any help

[Users] Do I really have to use ISO uploader?

[Blaster]

I’m trying to move from ESXi to KVM/OVIRT.   To attach an ISO to a CDROM under 
ESXi, I just have to add the NFS share with all my ISOs, then go to the CDROM 
and attach one of the ISO images and away I go.

Under OVIRT, it seems like I have to create yet another datastore, use 
engine-iso-upload which will create yet another copy of the ISO, before I can 
attach it to a virtual CD device.

Please tell me I missed something in my hours of searching that this isn’t 
true, that I don’t really have to duplicate each ISO that I already have on a 
NAS NFS share, to yet another copy that OVIRT can use.

There also doesn’t seem to be a nice way to take a disk image and simply click 
“add to inventory” like I can with ESXi, that I have to use image uploader to 
create yet another copy of the image and wait for it to copy a 100G file before 
I can create a VM out of it.

Thanks for any suggestions on making this process easier.

Re: [Users] Do I really have to use ISO uploader?

[Blaster]

After I emailed the list I was researching some other OVIRT related topic and 
came across someone’s blog that described how to do this..Pretty simple…
Create your ISO domain on local storage
cd to the path, then into images/----
Create your symlink here, and a couple seconds later the ISO shows up in the 
GUI.

Not horribly intuitive, but I can live with it.

Now, if there was only a simple way to create a VM out of an existing disk 
image, I’d be happy.

 Agreed. Many of us already have an existing directory of ISOs which is

 This is an issue which is on the To-Do list, but unfortunately didn't make 
 the first cut for 3.3.2 recently.
 
 From what I understand, it should not be terribly difficult to change oVirt 
 to utilize it. I believe it was Itamar who previously described a way on IRC 
 to use symlinks to refer to existing ISOs.
 
 It seems like most of the competition allows a VM to access any file path for 
 an ISO, rather than having to copy it into a storage domain first. That would 
 be much preferable in my opinion.

[Users] Building ovirt-guest-agent is destroying my VM!

[Blaster]

So this has happened twice nowRunning Windows 7/64 in a VM.

I git cloned the ovirt windows agent and installed the 3 Python 
applications as instructed in the README.


When I run the win-guest-agent-build-exe.bat file to create the exe, it 
gets to the line of:

adding python27.dll as a resource to virtguestservices.exe.

Then the cmd.exe window just hangs.  It can not be killed, nor can any 
other window.


The system will not shutdown, either from the Windows side or the VM 
side.  I had to power off from the GUI.


The first time this happened, the VM hung and became non-responsive.  
When I tried to reboot the physical machine, the physical machine would 
not reboot either.  Had to hit the reset button to get it back.


The second time this happened, ovirt was able to power off successfully, 
I decided to reboot the physical machine again, and again the physical 
machine hung shutting down and had to physically reset.


Both times when I tried to start the Windows 7 VM again, ovirt refused 
to start it.  I get the message

Failed to run VM Win7-01 (User: admin@internal).

So off to restore the VM for a second time

Any explanation how Python is able to destroy a VM like that?

Hi,

Just curious, is it really the porpoise of the snapshot to backup both
the vm and the application data? I think snapshot is appropriate to
backup the vm and the you should have your regular backup for the app,
as a database backup that can be done online. In this scenario you take
a backup of the vm when something changes (updates, new software,
configs, etc) and not all the time and do regular backups of the db as
it's the information that changes all the time.
I said this because I'm curious about the benefits of doing backups the
way it's been posted.
Regards,


Contrary to my other post, which was more educational than practical, 
yes, you generally would not back up app data via a hypervisor 
snapshot.  Generally you would only backup the OS disk and perhaps the 
application binaries.  This would be for quick restore of the OS and 
app, so you don't have to spend hours reconfiguring your OS.  
(especially Windows based OSes)


I also do an IN OS backup as well, for individual file restores in the 
instances you accidentally destroy something in /etc for example.

I guess I'm confused as to how Red Hat can be making statements that 
Ovirt is a viable alternative to ESXi when many simple things that ESXi 
users take for granted simply don't work or are non-existent under 
Ovirt.  I'm hardly a power user of ESXi, and I've only begun my Ovirt 
journey, but I've already come across the following:


1) No easy way to use an NFS share of ISOs to boot VMs with.  Have to 
create a data domain and custom build a symlink tree.
2) No way to take an existing VM disk image and add to inventory. You 
have to go through a process of importing it into a data domain.  This 
makes it very complex to pop a disk out of chassis and move the VMs to a 
new hypervisor and go.  Also makes DR more complex.
3) No way to make a backup of a guest using snapshots because you 
apparently can't delete the snap shots after you create them. (Must have 
been the same engineers who wrote ZFS and never imagined anyone would 
want to shrink a ZFS filesystem...)
4) There appears to be little or no documention on what you need to do 
to prep an Ovirt guest..  I still am not sure, and I've spent hours on 
Google trying to put it together...

Looks like you need
a) virt-IO drivers
b) Spice drivers
c) qemu-agent drivers which you must create your own build environment 
and build yourself
d) ovirt-agent drivers which you must create your own build environment 
and build yourself

e) have I missed anything?
Under ESXi it's right click, install. done.

Bob pretty much said it all for me already…I’m not so much as disappointed in 
ovirt development as I am the marketing of it.  ovirt is being marketed as an 
ESXi replacement when it surely isn’t.  Probably 90%+ of what ESXi is used for 
is virtualizing Windows.  Give ovirt in it’s current form to a typical Windows 
user and they’ll self destruct.

The first issue with the agents as I can’t even find any documentation on what 
agents really need installing, and what features I’m getting with that agent!

Another thing is, I would think that Fedora would be integrated enough with 
ovirt that it would be able to automatically detect it’s running on ovirt and 
install all the required agents automatically.

I forgot my number 5)  BIOS needs to work like a standard PC BIOS (as does 
ESXi) in allowing you to press F8 to get a boot menu or F12 for network boot.  
This run once stuff is silly.  It works fine the first time I create a VM as 
there’s no bootable OS on the datastore, but if I need to re-PXE boot a VM, 
then I have to Run Once..OK, fine, but when the PXE completes it reboots, back 
into network boot, then I have to kill the VM and restart it normally.  Under a 
PC (or ESXi) BIOS, I just hit F12, network boot, OS re-installs, then  reboots 
normally.  Much better user experience.   I gave our Red Hat sales people 
feedback on this issue and was told it’s not going to change. ___

Is there an index for all the documents on www.ovirt.org/cool_stuff?  Maybe I 
need new glasses, but the only way I come across those is in Google searches if 
I get the keywords right.
  
 
 Seabios has boot menu support on F12. I don't recall if we specifically 
 disable it, I think not

I will try to hit an F12 next time I boot to see if I get a menu, I don’t 
recall seeing any text on the screen that it’s there.

Yes, that's the behavior on both ovirt and ESXi when creating a new VM.  
The problem is when you need to reinstall that VM.  On ESXi I can hit 
F12 on boot to PXE boot, OS re-installs, then boots normally to disk.  
On ovirt, I have to select Run Once, move PXE to the top, re-install, 
when the installer auto reboots, it goes back into PXE mode and starts 
reinstalling again.  I have to watch the console and power off at the 
right time, then power back on in normal mode.


A better behavior for Run Once would be just that...Run once...If the 
guest reboots Run Once should power off, or go back to normal boot 
behavior.  But I suppose that depends upon what your definition of Run 
Once is.


The ESXi BIOS is a Pheonix BIOS and in this case, functions just like a 
bare metal BIOS, like the ovirt Sea BIOS should :)

Re: [Users] Agents for Windows

This setting is a PER GUEST setting, not system wide.  On guests you 
reboot frequently, don't set anything.  On guests you need to change 
boot options frequently, change it to what you want.


We have about 6000 guests on ESXi, have not had any issues working this 
way.  On production VMs that get built once and never touched for years, 
don't change anything.  On dev VMs that get rebuilt frequently, we add a 
delay.

 I'll disagree a tiny bit here. One *really annoying* quality of
needing to use F2/F8/F12 during Windows bootup in a VM (including
ESX/vSphere) is that sometimes it can be impossible to be quick

begun. By the time you can get a console focus it's too late. That
can be enormously frustrating, and Run Once does help with that.

On ESXi
Guest menu - edit settings - Options - boot options - boot

[Users] Solaris 11.1 ISO panic on boot

[Blaster]

I have a Solaris 11.1 system running on a nice piece of hardware that I’d like 
to make better use of.  I would like to virtualize it under ovirt.

I created an ovirt guest using the RHEL 64 bit template.  I attached the 
Solaris 11.1 ISO and booted.  As soon as the Solaris banner is displayed, poof, 
kernel panic.

Of course every whizzes by so fast I have no chance of getting a screen shot.

Has anyone been successful in boot Solaris 11.1 under ovirt?  Should I have 
picked a different template?

Re: [Users] Agents for Windows

[Blaster]

From RHEL 6.5 release notes...


 Windows Guest Agent Fully Supported

The Windows guest agent is now fully supported and delivered with its 
own installer in the Supplementary channel together with virtio-win drivers.

[...]


 Application-Aware|freeze|and|thaw|on Microsoft Windows with VSS
 Support on*qemu-ga-win*

VSS (Volume Shadow Copy Service) is a Microsoft Windows API that allows, 
among other things, the notification of applications for proper, 
consistent freeze and thaw operations. With this feature, snapshots 
taken while the virtual machine is running are consistent through the 
whole stack (from the block layer to the guest applications) and can be 
used for backup purposes. For more information, see theVirtualization 
Administration Guide 
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization_Administration_Guide/sub-sect-qemu-ga-freeze-thaw.html


Is there any issue with using these drivers with OVIRT?  (since ovirt is 
upstream of RHEV, it should work, right?)

I know, the answer will be no...

Since you're already building the Windows drivers on some (set of)

you create a VM, add a disk, then copy over the converted image onto the 
oVirt created image and away you go.


I did this twice under oVirt 3.3.1 and it worked great.

The original oVirt 3.3.1 system that has now been upgraded to 3.3.2 
still boots this same disk image just fine.


I'm guessing it's upset because apparentsize and truesize are different?

Why did 3.3.1 seem not to care but 3.3.2 does now?

Any way I can true these up?  I've tried a few things with qemu-img but

Subject: [Users] virt-io SCSI duplicate disk ID

So twice now under oVirt 3.3.2 I have added 2 virtio-scsi devices to a single
virtual host.

After doing so, the VM would fail to boot due to duplicate disk ID. The first
time I thought it a fluke, second time’s a bug?

Fortunately they were empty data disks and I was able to get around the
problem by deleting one and recreating it.

[Users] Horrid performance during disk I/O

[Blaster]

This probably more appropriate for the qemu users mailing list, but that list 
doesn’t get much traffic and most posts go unanswered…

As I’ve mentioned in the past, I’m migrating my environment from ESXi to oVirt 
AIO.

Under ESXi I was pretty happy with the disk performance, and noticed very 
little difference from bare metal to HV.

Under oVirt/QEMU/KVM, not so much….

Running hdparm on the disk from the HV and from the guest yields the same 
number, about 180MB/sec (SATA III disks, 7200RPM).  The problem is, during disk 
activity, and it doesn’t matter if it’s Windows 7 guests or Fedora 20 (both 
using virtio-scsi) the qemu-system-x86 process starts consuming 100% of the 
hypervisor CPU.  Hypervisor is a Core i7 950 with 24GB of RAM.  There’s 2 
Fedora 20 guests and 2 Windows 7 guests.  Each configured with 4 GB of 
guaranteed RAM.

Load averages can go up over 40 during sustained disk IO.  Performance 
obviously suffers greatly.

I have tried all combinations of having the guests on EXT 4, BTRFS and using 
EXT 4 and BTRFS inside the guests, as well as direct LUN.  Doesn’t make any 
difference.  Disk IO sends qemu-system-x86 to high CPU percentages.

This can’t be normal, so I’m wondering what I’ve done wrong.  Is there some 
magic setting I’m missing?

Re: [Users] Horrid performance during disk I/O

Sorry I missed your original post.   But at least I know now I’m not the only 
one suffering this problem.  I would be interested in knowing how wide spread 
this is, and why there aren’t people screaming up and down on the qemu mailing 
list about this issue?  My system board is a Sabertooth X58 using the ICH10r 
chipset.

I wish I hadn’t of destroyed my AMD oVirt system yesterday, I didn’t notice any 
issues on there, but I didn’t push the IO very hard on it.

Have you opened a BZ on this issue?

I wonder if it’s possible to down rev qemu to see if this is a recent issue, or 
will oVirt have an issue?

I've been trying to get some real numbers of the performance differences

Re: [Users] conversion of ESXi 5 centos VM to fedora19 ovirt host-- import failed

[Blaster]

I haven’t tried this yet, but if I had to move a VM from ESXi to oVirt this is 
how I would do it…
(actually, this is how I did it with Windows 7 guests…)

Shutdown guest on ESXi  (or use GhettoVCB to make a snapshot backup if you 
don’t want an outtage) 
NFS copy guest from ESXi server to temp storage somewhere
qemu-img convert guest.vmdk -O raw guest.raw
Create an oVirt guest with the appropriate OS type
Add a disk of the same GB to the guest
After oVirt finishes creating the disk, copy the guest.raw file over the disk 
image oVirt made
boot guest and install qemu-agent, ovirt-agent, spice-agent (or better yet, do 
this before you shutdown on ESXi)
remove VMware tools.

The importing and virt2v procedure seems far to complex and error prone to me.

I finally found time to switch from virtio-scsi to virtio.  Seems to have make

The windows VMs boot faster, web pages load faster, same with the Fedora 20

Everything just feels smoother.

I found this interesting presentation:

Claims virtio blk and scsi are the same speed.  Although, it doesn’t mention if 
this was with or without data plane enabled.

When will data plane be the default?

I don’t think that’s what we are looking for.  With this process, if I have an 
X size virtual disk, I have to come up with X+2X more storage to go through 
this silly import process. With ESXi, I just right click, add to inventory and 
I’m off.

Right now, I’m looking at moving my AIO configuration to a new host.  I’ll have 
to create the new AIO host, create a new storage domain on the old disks, 
create new VMs that look like the old ones, create new virtual disks, then go 
rummage around the storage, figure out what’s what in these user unfriendly 
UUID names, then move the old images onto the new ones.

With ESXi, I just reinstall the hypervisor, create the new VM, then right 
click, add to inventory on the old disk image, and I’m done.

https://bugzilla.redhat.com/show_bug.cgi?id=1049604

The concept of storage domains seems rather clumsy and limited to me.

I've been looking for a similar scheme for the last year.  It was not 
(really) possible in the past as there wasn't any way to destroy a 
snapshot w/o shutting down the VM.   Is this still the case, or are snap 
shots fully implemented now?


Basically, I'd like to:
Tell VM to flush it's buffers
suspend VM
take snap shot of boot virtual disk
resume VM
backup the virtual boot disk from the Hypervisor using standard commands 
(tar, cp, whatever)

destroy the snapshot

This would at least give some BMR capabilities of your VMs.

Ideally, I'd also like to be able to create a snapshot from within the 
VM, do a yum update, see if I like it or not, if I do, then destroy the 
snap shot.  If I don't, I want to promote the snapshot and boot from 
that, then destroy the original.
(Yes, I know, BTRFS is supposed to be the solution to this with in the 
VM at some point, isn't it?)


I have looked at the oVirt backup API wiki, but the code examples look 
more like pseudo code than real world examples.

Thanks for the tip.  This didn't work for me this time.  My AIO setup 
started out with 3.2, upgraded all the way up to 3.5,  I was missing the 
OVF files, so I couldn't import the storage domain.  So I bit the bullet 
one more time and did it the hard way (created new VMs, disks, then 
copied over the old image).  This time I created a storage domain for 
each VM so I can import them into a new setup individually.


Btw, what does the (master) designation by one of the storage domains 
mean?  When I deleted one that was a master, it just moved to another 
domain.

Hi,

Thanks.

This is the procedure I've used several times from ESXi, should be the 
same with any vmdk.


Shutdown guest on ESXi  (or use GhettoVCB to make a snapshot backup if you 
don’t want an outtage)
NFS copy guest from ESXi server to temp storage somewhere
qemu-img convert guest.vmdk -O raw guest.raw
Create an oVirt guest with the appropriate OS type
Add a disk of the same GB to the guest
After oVirt finishes creating the disk, copy the guest.raw file over the disk 
image oVirt made
boot guest and install qemu-agent, ovirt-agent, spice-agent (or better yet, do 
this before you shutdown on ESXi)
remove VMware tools.

This is using an AIO configuration in a lab, no chance of a migration storm.  
I’m just looking for an easy way to move a VM around if I need to.  1GB 
ethernet is getting mighty slow these days, and any other shared storage is 
horribly expensive for a consultant’s home lab. 10GB NIC cards are becoming 
affordable, but the switches, not so much.

 Creating storage domain per vm is not a good idea.
 
 The system is expecting all storage domain to be accessible by all hosts. So
 if you have multiple storage domains and one become inaccessible, a host
 may become non-operational, which will cause migration storm from this host
 to other hosts. Basically, the more storage domains you have, your system
 is more fragile.
 
 Create new storage domains only when you must (e.g. separating testing and
 production environments). For importing and exporting vms, you can use the
 export domain.

[ovirt-users] bond mode balance-alb

[Blaster]

I’m looking to setup bonding.  I’m using Dell 2824 switches which support LAG 
(static 802.3ad apparently?) but not LACP (dynamic 802.3ad).  Fedora only seems 
to support Dynamic mode from what I can tell.

The next best choice seems to be balance-alb, but for some reason it’s not 
available as a mode in the drop down.  Any reason why it’s missing?  If I 
select custom and enter balance-alb, is that supported?

Re: [ovirt-users] Autostart vm's at host boot on local storage

[Blaster]

There was a discussion on this list a year or so ago about this.  I 
believe one of the developers responded that oVirt has no facility to

I use the following 2 scripts to start VMs automatically when my AIO

somewhere on the net, I don't remember where anymore.

I run the first script out of cron every 15 minutes.

#!/bin/bash

do
echo Do I need to start  ${vm}
/root/bin/vm_up ${vm}
if [ $? -eq 1 ]; then

echo ${TEXT}
echo ${TEXT} | mailx -s ${TEXT} r...@domain.com
fi
done

#!/usr/bin/python

import sys, string

VM_NAME = sys.argv[1]

api = API(url=URL, username=USERNAME, password=PASSWORD, ca_file=CA_FILE)


try:
 if api.vms.get(VM_NAME).status.state != 'up':
 print 'Starting VM'
 api.vms.get(VM_NAME).start()
 print 'Waiting for VM to reach UP status'
 while api.vms.get(VM_NAME).status.state != 'up':

Re: [ovirt-users] 1. Re: ??: bond mode balance-alb (Jorick Astrego)

[Blaster]

Thanks for your thoughts.  The problem is, most of the data is transmitted from 
a couple apps to a couple systems.  The chance of a hash collision (i.e., most 
of the data going out the same interface anyway) is quite high.  On Solaris, I 
just created two physical interfaces each with their own IP, and bound the apps 
to the appropriate interfaces.  This worked great.  Imagine my surprise when I 
discovered this doesn’t work on Linux and my crash course on weak host models.

Interesting that no one commented on my thought to just do the bonding at the 
guest level (and use balance-alb) instead of at the hypervisor level.  Some 
ESXi experts I have talked to say this is actually the preferred method with 
ESXi and not to do it at the hypervisor level, as the VM knows better than 
VMware.

Or is the bonding mode issue with balance-alb/tlb more with the Linux TCP stack 
 itself and not with oVirt and VDSM?

  Dan,
 
  What is bad about these modes that oVirt can't use them?
  I can only quote jpirko's workds from the link above:
 
  Do not use tlb or alb in bridge, never! It does not work, that's it. 
  The reason
  is it mangles source macs in xmit frames and arps. When it is possible, 
  just
  use mode 4 (lacp). That should be always possible because all enterprise
  switches support that. Generally, for 99% of use cases, you *should* 
  use mode
  4. There is no reason to use other modes.
 
 This switch is more of an office switch and only supports part of the
 802.3ad standard:
 
 
 PowerConnect* *2824
 
 Scalable from small workgroups to dense access solutions, the 2824
 offers 24-port flexibility plus two combo small?form?factor
 pluggable (SFP) ports for connecting the switch to other networking
 equipment located beyond the 100 m distance limitations of copper
 cabling.
 
 Industry-standard link aggregation adhering to IEEE 802.3ad
 standards (static support only, LACP not supported)
 
 
 So the only way to have some kind of bonding without buying more
 expensive switches, is using balance-rr (mode=0), balance-xor (mode=2)
 or broadcast (modes=3).
  I just tested mode 4, and the LACP with Fedora 20 appears to not be
  compatible with the LAG mode on my Dell 2824.
 
  Would there be any issues with bringing two NICS into the VM and doing
  balance-alb at the guest level?

[ovirt-users] Disable HTTP Strict Transport Security?

[Blaster]

I've been having this problem for a while, but it's now impossible to 
get around as all my browsers have updated to prevent by passing HSTS.


I must be doing something wrong  as I don't see anyone else complaining 
about this in regards to Ovirt...


I'm running a Ovirt 3.5.4 All In One setup.  No matter what browser I 
use, I can no longer get to the GUI because it appears 3.5? started 
enforcing HTTP Strict Transport Security and since Ovirt uses self 
signed certs, the browsers are refusing to let me through.  It appears 
newer browsers no longer allow you to click through unsigned certs of 
HSTS is enabled.


What do I need to do to get around this?   What am I missing since no 
one else seems to be having this problem.


Thanks...

What I would suggest is:

http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm

- fedup from fc20 to fc22 directly, without the fc21 step
- run rpmconf -a and update relevant config files (be sure to not 
just overwrite them!)

- run postgresql-setup --upgrade
- run engine-setup

I suggest to update to fc22 directly because there aren't FC21 builds 
of ovirt engine and the fedup process may not work as expected with 
missing repos.


If the upgrade fails, you can restore the disk image created with 
clonezilla and retry with a different procedure.


If you hit any issue or if you succeed let us know!


So I did a fedup from 20 to 22, which went fairly well. I did have 
some issues though:


named was missing some libraries after the upgrade.  Removing named 
and reinstalling has fixed that up.


rpmconf -a is giving me the following error:
# rpmconf -a

So not sure what's going on there.  I do have PackageKit-glib-devel 
installed.


 postgresql-setup upgrade

Cannot upgrade because the database in /var/lib/pgsql/data is not of
compatible previous version 9.2.

What do I do about this?

I did engine-setup afterwards and everything seems to be running fine.

I did have to set my host CPU type back to Sandybridge as it wasn't 
recognizing my I7 4790K.  Seems to be a known issue.


I also have explanation points next to all my VMs stating that my time 
zone configuration differs between the VM config and the guest config, 
which they do not.




Finally having a chance to get back at this.   This ended up not going 
anywhere near as well as I had originally thought.


The reason why the Postgress upgrade was failing was because I was still 
running 9.3 for some reason after the fedup upgrade.  As I started 
diagnosing the known NFS server problem, I discovered after the fed22 
update, it apparently only updates you to the base Fedora 22 packages. 
You then need to do a dnf update to get the latest. Which then fixed my 
NFS problem, but then vdsm refused to connect to the database.  It was 
at that point I discovered my installed version of Postgress was now @ 
9.4, instead of 9.3.  Not sure how I got to 9.3, as I thought Fedora 20, 
which is where I came from has 9.2, and Fedora 22 had 9.4.


So now I did the Postgress upgrade, which worked as expected above. But 
vdsm still would not connect to the database.  After googling that 
issue, the only suggestion I saw was to remove the password from the 
vdsm conf file and re-run engine setup.  That really upset Ovirt and it 
wiped out everything and proceeded to start with a fresh configuration, 
wiping out my datacenter.


I do run a nightly ovirt backup, which I attempted to restore from, but 
it wouldn't let me do that as my backup which was from the previous 
night was for 3.5, and I was now at 3.6.1.  So much for backups.


It was at that point I just decided to investigate Hosted Engine, seeing 
as I was needing to start from scratch.  After spending several hours 
researching that, it appears HE is know where near ready for any sort of 
daily driver.  The WIKI how to seemed severely out of date and I 
couldn't find a usable engine appliance ISO that seemed to be ready to 
with out hours or days of additional hacking.


So in the end I just re-ran the All-In-One setup and spent a couple 
hours rebuilding my datacenter.


So to the above steps, a dnf update needs to added as a step after the 
fedup reboot.

Hi, upgrade from FC20 to FC22 has not been tested and you're welcome 
to help testing it.

What I would suggest is:
- make an image of your existing engine (I suggest clonezilla for 
doing it)
- install ovirt-release36 from 
http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm

- fedup from fc20 to fc22 directly, without the fc21 step
- run rpmconf -a and update relevant config files (be sure to not just 
overwrite them!)

- run postgresql-setup --upgrade
- run engine-setup

I suggest to update to fc22 directly because there aren't FC21 builds 
of ovirt engine and the fedup process may not work as expected with 
missing repos.


If the upgrade fails, you can restore the disk image created with 
clonezilla and retry with a different procedure.


If you hit any issue or if you succeed let us know!


So I did a fedup from 20 to 22, which went fairly well. I did have some 
issues though:


named was missing some libraries after the upgrade.  Removing named and 
reinstalling has fixed that up.


rpmconf -a is giving me the following error:
# rpmconf -a
/usr/libexec/pk-command-not-found: error while loading shared libraries:

So not sure what's going on there.  I do have PackageKit-glib-devel 
installed.


 postgresql-setup upgrade

Cannot upgrade because the database in /var/lib/pgsql/data is not of
compatible previous version 9.2.

What do I do about this?

I did engine-setup afterwards and everything seems to be running fine.

I did have to set my host CPU type back to Sandybridge as it wasn't 
recognizing my I7 4790K.  Seems to be a known issue.


I also have explanation points next to all my VMs stating that my time 
zone configuration differs between the VM config and the guest config, 
which they do not.

Hi Michal, 

I did try a clean install.  Both an upgrade and a fresh install cause a blue 
screen.How do I pin point the blue screen?  I’m guessing it’s a QEMU issue 
with Win 10.  I’m on Fed 22, how do I get a newer QEMU than what’s in the 
distribution?  or should I just upgrade to Fedora 24?

I am running an application called Blue Iris which records video from IP cameras.This was working great under Ovirt 3.6.3 + Windows 7.  Now I’ve upgraded to Windows 10 and as soon as the Blue Iris service starts, the VM blue screens.I talked to the software vendor, and they said it’s not their problem, they aren’t doing anything that could cause a blue screen, so it must be  driver/memory/hardware problem.  They say the application works just fine under Windows 10.So thinking maybe the upgrade went bad, I created a new VM, used e1000 and IDE interfaces (i.e., no Virtualized hardware or drivers were used) and re-installed Blue Iris.Still blue screens.How do I go about figuring out what’s causing the blue screen?  Thanks….___

[ovirt-users] Windows 7 to 10 Upgrade fails

[Blaster]

I'm trying to update some Windows 7 VMs before the free upgrade period ends.

It appears Windows 10 has an issue with KVM during the upgrade, and 
according to this thread, 
http://ubuntuforums.org/showthread.php?t=2289210=13334367#post13334367 
, you need to specify the CPU type as core2duo for the VM, perform the 
upgrade, then switch it back.


Is there anyway with ovirt to set the CPU type to core2duo for a single 
VM without having to shutdown the entire cluster, change it for the 
cluster, do the upgrades, then change it all back?


Thank you

We currently have too many problems with fedora to call it even 'Technical

You can still use the nightly snapshots, and most things work, more-or-less,

[ovirt-users] Get UU

[Blaster]

I need to create an old oVirt Windows VM.  The VM has an old licensed product 
that we can no longer get a licensed reissued for.  It looks like I need to 
feed back the original qemu UUID that was used when the VM was created.

I have an engine config backup and a backup of the oVirt storage domain.

I viewed the engine backup, but the format as-is doesn't give any obvious 
configuration details of the VMs at the time of the backup.  Is the UUID as 
obvious as the file name of the VM's boot volume UUID name?

[ovirt-users] 4.2: Can't add local storage

Fresh install of 4.2 self hosted engine.

Right after install, I tried to add local storage.  I tried to put the 
hosted engine VM into maint mode, but it forever just sat there in the 
going into maint state, and never actually went into maint state.


The default Datacenter was in uninitialized state.

So I tried adding an NFS storage domain, which initialized the 
datacenter.  Now when I try and put the hosted engine VM into maint mode 
I get: Cannot switch the hosts to maintenance mode. There are no 
available hosts capable of running the engine VM.


What am I doing wrong?

The re-initialize data center option is greyed out.

I can’t add any other storage domains because there isn’t a master.

I keep getting pop up errors “failed reconstructing master storage domain for 
datacenter default”.

Anyway to get this back?

I don’t see anything in the engine or vddm logs as to why it’s failed.

I am running a single host configuration with local SATA disk.  When I need to 
change hosts, I generally just move the disks (or copy data via NFS) to the new 
host, create new VMs, then move the old VM disks into the new VM directory with 
the new file names and boot. ___

Re: [ovirt-users] Assign external IP to VM

[Blaster]

You're over thinking this.  Just create an ifcfg script just enough so 
the interface plumbs, with no IP, then add it do your datacenter, with 
something like dmz or internet as it's name.  Then add the NIC to the VM 
and plumb it up.


Since there's no IP plumbed in the hypervisor, there's no way it can be 
access from the network.

You need to add a second host allowing the hosted engine to migrate in 
order to move the host to maintenance.




This is bad terminology on oVirt's part.  I was wanting to add local 
SATA disk as I have a 1 node environment with no shared storage.  To 
accomplish what I really wanted to do, I had to change the datacenter 
storage type to local storage, the a local file system option appeared 
in the create new storage domain diaglog.


oVirt/RHEV team really needs a good documentation writer, as this 
storage option isn't even documented in the storage section of the 
administration guide.


Installing my first 4.2 system, and it's obvious the documentation 
writer hasn't sat down and down and done a clean install.  Lots of stuff 
missing.


I've never looked at Proxmox, but it's taking the hobbyist and small 
environment virtualization world by storm, especially after Xen's latest 
licensing changes.  oVirt should have this.  But it's way too 
complicated and way too fragile and way under documented.

I installed bare Win 10 with no VirtIO drivers (ie, using e1000 for network and

The other thing you could possible try is a different chipset type.  I’m using

of it saying it was known to work on ESXi and they don’t have any device 
drivers nor where they doing anything but standard Windows library calls, so 
they pushed it back to a Hypervisor issue.

It’s known to work with ESXi and Xenserver.   I haven’t heard either way on 
Proxmox.  I’m guessing there’s some issue with QEMU.

Good to know.  QEMU issue I'm going to assume.   I wonder if 
virt-manager and Proxmox would show the same failures, they should.

[ovirt-users] 3 strikes....

[Blaster]

Well, I've spent the last 2.5 days trying to get oVirt 4.2 up and running.

I sneeze on it, vdsm has a conniption and there appears to be no way to 
recover from it.


1) Install 4.2.  Everything looks good.  Start copying over some 
data..accidently wipe out the master storage domain...It's gone. The 
only method google could suggest was to re-initialize the data center.  
Great.  I'd love to!  It's greyed out.  Can't get it back...Try several 
hosted-engine uninstall methods, including


/usr/sbin/ovirt-hosted-engine-cleanup and wiping out the storage.

re-run hosted-engine --deploy
  All I get over and over in the vdsm log file while waiting for vdsm to become 
operational is..

sigh...reinstall 7.4 and do it all over again.

2) copying data to master storage pool.  Didn't wipe it out this time, but 
filled the volume instead.  Environment freezes.
 vdsm can't start...infinite loop waiting for storage pool again.  Try clean up 
and redeploy.  Same problem as above.
7.4 reinstall #2 here we go...

3)Up and running again.  Forgot to add my NIC card. Shut it down.  Boot back 
up.  vdsm sees new network interfaces.
for some reason, it switches ovirtmgmt over to one of the new interfaces which 
doesn't have a cable
attached to it.  Clean up ifcfg- files and reboot.  ifcfg-ovirtmgmt is now 
gone.  recreate and reboot.  Interface
comes alive, but vdsm is not starting.

Re: [ovirt-users] oVirt 4.2.0 is now generally available

[Blaster]

What a great Christmas present!

I'm still running 3.6.3 All-In-One configuration on Fedora 22.  So it 
looks like I'll be starting from scratch.


Is there any decent way yet to take my on disk VM images and easily 
attach them?  I put in an RFE for that which looks like it didn't make 
it into 4.2, now slated for 4.2.1.


The old way I used to do this was to create new VMs with new disks, then 
just copy over my old VMs to the disk files of the new VMs.  I'm 
assuming I'll still have to use that method.

I need to create an old oVirt Windows VM. The VM has an old

that was used when the VM was created.

I have an engine config backup and a backup of the oVirt storage
domain.

I viewed the engine backup, but the format as-is doesn't give any
obvious configuration details of the VMs at the time of the
backup.  Is the UUID as obvious as the file name of the VM's boot
volume UUID name?



I think it's the field 'vm_guid' in the table 'vm_static'.

You can restore the backup on a temp vm somewhere - make sure it has no
access to your hosts so that the engine will not start to manage them -
or just look at the db dump. The backup is a tar file, and you can look
at db dumps inside it using 'pg_restore filename | less'.


The guest UUID is configurable per VM in Edit dialog, you can use
a custom value



Thank you, I was able to get the UUID back!
