No there isn't but you can script it using ovirt-shell or a python script.

Please note that the above page is very old and unmaintained, and should only
be used to get some detailed reference about the process. It also mentions in
bold, close to the beginning, "This howto is intended for oVirt 3.1 version."

Please use the tool engine-backup and related pages about it.

If you encounter problems please report them.

Thanks!

By all means, use oVirt 3.6. It works great and is recommended for
production use. I highly recommend you deploy it on RHEL/CentOS 7.2,
for best results.

Re: [ovirt-users] matching / mapping ovirt storage domain images to VMs

[Charles Kozler]

Pavel -

This works if engine is up. What about if it is down? Is there no way to
easily correlate? Like maybe through vdsClient to check with VDSM on the
engine directly?

[ovirt-users] packet loss ingress to engine VM

[Charles Kozler]

I cannot figure this out for the life of me but its been an issue. it
eventually resolves itself once everything has "settled" after I bring the
hosted-engine VM up but it takes anywhere between 15 minutes and 1 hour to
completely settle

http://imgur.com/a/o4S5m

The picture is the best way I can describe it. From the node the engine is
running on I ping the engine VM and packet loss is great. When I ping FROM
the VM out to the outside world (or any IP really) there is no packet loss

I have ruled out physical connectivity issues and RSTP/STP is not enabled
on the switches that the ovirtmgmt network is connected to

This causes a problem because the inbound checks from the nodes fails (I
guess you use ICMP?) and then it starts to enter a constant flap state
where the engine keeps migrating around

Re: [ovirt-users] Windows Server 2012R3 guest: BSOD

[gregor]

Hi,

I will install in the next few days a new host where Windows Server 2012
R2 should run. On my test machine I had run qemu with the cpu "Westmere"
to use Window Server 2012 R2, all other CPU's will bring a BSOD, reboot
loop or other issues.

Maybe this will help.

[ovirt-users] Startup VM after host reboot

Hi,

I use oVirt all-in-one 3.6, is there a setting to automatically start
selected VM's when the host has rebooted? This can happen on power

[ovirt-users] Move from Gluster to NFS

[Christophe TREFOIS]

Dear all,

I currently have a self-hosted setup with gluster on 1 node.
I do have other data centers with 3 other hosts and local (sharable) NFS 
storage. Furthermore, I have 1 NFS export domain.

We would like to move from Gluster to NFS only on the first host.

Does anybody have any experience with this?

Thank you,

[ovirt-users] 3.5 or 3.6 For Production System?

[Charles Tassell]

Hi Folks,

  I'm setting up a small virtualization system that will start with one 
or two hosts and then probably grow to 4-5 hosts.  We will eventually be 
using a shared iSCSI datastore, but right now I'll probably just use 
NFS4.  I'm wondering if I should stick with my plan of using oVirt 
3.6.2, or should I start of with 3.5 and upgrade at a later date.  Is 
3.6 generally stable enough for production use?  We're not doing 
anything very complicated, just running a few Linux webserver VMs.  No 
high availability or auto-deployment type stuff.

Hi,

When I attached my NFS export domain to a data center, I see the following 
message in the events log

"The Storage Domain does not contain any OVF_STORE disks. Usually the Storage 
Domain does not contain OVF_STORE disks when the Storage Domain has been 
previously managed with a Data Center version lower then 3.5."

However, the export domain and oVirt have been used below 3.5.

Is this normal behavior for an export domain or is there something I should do 
to fix it?

I can export / import VMs from / to the export domain just fine (until now)

Re: [ovirt-users] Clone / New VM from Template changing network interfaces

[Raz Tamir]

Hi Mark,
The problem is that you need to seal the source vm before creting the
template.

http://www.ovirt.org/Sealing_Linux_VM

Thanks,
Raz Tamir
Red Hat Israel
oVirt Engine Version: 3.5.0.1-1.el6

When cloning or creating a new vm, the network interfaces in
/etc/udev/rules.d/70-persistent-net.rules is getting changed - rendering
the new new VM un-networkable.

The original file looks like this:

[image: Inline image 1]

However, once the VM is either cloned or a new VM created from a template
of this source VM, the file looks like this:

[image: Inline image 2]

The 'correct' interfaces are still there, but out of sequence and there are
two additional interfaces that do not belong there.

Ovirt admin console is showing the correct number of interfaces as seen in
this image:

[image: Inline image 3]

Any idea what is causing this?

Thank you for your assistance.

[ovirt-users] Windows Server 2012R3 guest: BSOD

[Alan Murrell]

Hello,

oVirt: 3.6.1
qemu: 2.3.0

I installed a Windows Server 2012R2 guest.  The install is good, but 
when the guest boots into Windows, the Server 2012 version of the BSOD 
comes up,then goes to a "DOS" screen that has an error code '0xc001'


I have tried using a VirtIO HDD and IDE; both result in the same error.

Any ideas what the issue might be?  CPU is Sandybridge, if that makes a 
difference.

Alan
