You can use cloud-init to provision an IP address to a machine. Or
integration with OpenStack Neutron would probably allow for that too
(via DHCP I imagine).

Any reason why you don't just use static DHCP leases?

Thanks for your help, Markus.  I'll think it through over the weekend
and see if anyone else has any bright ideas to get me out of this mess
and give it a shot Monday.

Have a good weekend :)

Thanks, looks like that may be the issue.

Is there any way I can cancel the current operation (it is still ongoing)
so that I can get the hosts upgraded?

I don't know if you have a solution, but I hit this on the last
upgrade. I just updated ovirt-engine-setup and ran engine-setup which
pulled in all the required packages properly.  This is the recommended
procedure from the upgrade notes.

As far as my understanding goes, this is correct.

In my environment at least, whenever as VM is created through the web
UI it is cloned and I can delete the template.  By default, the API
doesn't seem to clone the disk, but this can be specified.

[ovirt-users] Failed migration - Migration is stuck

[Ollie Armstrong]

I'm having some issues with a couple of VMs in my cluster that cannot
be live migrated between hosts.  It appears to be the issue that is
referenced by https://access.redhat.com/solutions/870113 and
https://access.redhat.com/solutions/1159723.

I currently have a dedicated 1Gbps network for migrations and have
modified some of my vdsm settings so that my vdsm.conf looks like
this:

[vars]
ssl = true
migration_timeout = 600
migration_max_bandwidth = 100
max_outgoing_migrations = 3
migration_downtime = 1000

[addresses]
management_port = 54321

The issue was happening before the configuration changes too.

The relevant lines from my vdsm.log from the host that the VM is being
migrated from: http://ix.io/xeT

Has anyone been able to resolve this or come up with a workaround for
this problem?  I understand that it is because the migration cannot
occur as fast as the changes in the VM are happening so this could be
difficult to get working.  Some downtime is acceptable for these VMs,
so if there are further config changes that can be made which allow
for more downtime then I would consider that a solution.

I've experienced a similar thing before and referred to this [1]
comment on BZ1302215 to help me out.  Followed those steps and my

Thanks for the reply Gonza.  When you've quoted what you've used, what

[ovirt-users] Using REST API to get a proxyticket

[Ollie Armstrong]

Hi all,

I'm attempting to use the REST API to get a proxy ticket as BZ1181030
[0] has added support for, but I am unable to find _any_ documentation
on how to use this new API call.

All I've found is the git commit message in gerrit [1].  Not quite
understanding how to interpret this, I've attempted to POST the
following:



As well as:

  ticket_content  

Both of these, and indeed using any other data I can think of, results
in an NPE being logged in engine.log.  I've uploaded my engine.log [2]
which is produced when I POST "" to the endpoint.

Is anyone able to tell me how to use this endpoint?  I'm assuming I
get the NPE because I'm not POSTing the correct data.  The overall
goal of this is to be able to embed a NoVNC console in our own web UI,
this is the last piece of the puzzle for me to implement this.

Thanks,
Ollie

[ovirt-users] Hosted engine storage "locked"

[Ollie Armstrong]

Hi,

I've updated from 3.6.1 to 3.6.2 and was hoping that the issue with
the hosted engine storage on FC not being imported would be solved.
It managed to start the import but now my storage has been stuck in
"Locked" for weeks.  None of the options in the web UI are available
except right click "Destroy".

Is there any way to restart the import process so maybe I can keep an
eye on the logs and find the issue?

Cheers,
Ollie

[ovirt-users] [Rest API / Python SDK] Setting VM Video Type

[Ollie Armstrong]

Hi everyone,

I'm looking for a method of settings the VM's video type to QXL from
the Python SDK, which doesn't appear to be possible in any way.
Whenever I set the graphics protocol to VNC it defaults the video type
to CIRRUS.  I'd like to use QXL with VNC, which is possible to set
using the console's web UI.

Has anyone achieved this before?  Using the "SPICE + VNC" option with
QXL would also be acceptable, but the API doesn't seem to accept that
value for the graphics protocol.

Cheers,
Ollie

Thanks, Juan.  I didn't see that method.

I've tried to use your suggested script and I get a 500 error back
from the server.  The /var/log/ovirt-engine/engine.log shows the
reason to be 'Mapping exception while processing "POST" request for
path "/vms/361e911f-8d6d-479e-b399-526507f24dea/graphicsconsoles"'.
Any idea why I would be getting that?

Re: [ovirt-users] MAC OS

[Ollie Armstrong]

As far as I am aware, the OS X EULA requires installation to be on
Apple branded hardware.  So unless you're oVirt Host is running on
Apple hardware you'd be breaking the EULA of OS X.  This is likely why
it isn't part of the OS option list in oVirt.

[ovirt-users] oVirt 3.6 hosted engine VM not showing

[Ollie Armstrong]

Hello,

Just installed a fresh deploy of oVirt 3.6 hosted engine and the engine VM
is not displaying in the VMs tab of the web UI (and also not listed in the
API response).  The host that it is running on shows a VM count of 1, but
the VM itself is not displayed.

The engine VM used to display in 3.5 but it no longer appears to in 3.6.
The storage method for the engine is the new FC if that's relevant.

Unsure if this is a bug or a feature, this has been mentioned a few times
in the IRC channel so it doesn't appear to just be affecting me.  Seems odd
that the VM count and the actual VMs list don't match up.

Cheers,
Ollie
