Any way I can obtain an oVirt T-shirt?
by Yair Zaslavsky
Hi guys,
I signed up to some meetups in my residential area, and I am considering to give lecture that relates to oVirt.
Can I obtain an oVirt t-shirt somehow so I can wear for the presentation? (Well, I can wear one of my Red-Hat T-shirts, but as I plan it be in context of open source, I would prefer oVirt)
Cheers,
Yair

I'd welcome any details on this "stalled file descriptor" problem. Is
there a bug filed with some details like logs, sysrq-t and maybe even
tcpdumps? If there is an easy way to reproduce this behaviour, I can
surely look into it and hopefully come up with some advise or fix.

Upgrade order 3.4.2 -> 3.5.x

Hi,
maybe a stupid one. Just want to make sure that nothing goes wrong. We
plan to make a rolling upgrade of our landscape going to 3.5.1 in december.
So we always need some hypervisor nodes up and running during the
process.
Looking at older posts I assume that upgrading the engine should be
sufficient, while hypervisor nodes with vdsm 4.14.17 (from 3.4 repos) and
the active VMs keep on running. The start of the engine after the upgrade
should catch up and resync all states.
Afterwards I clean hypervisor hosts one by one and clean/reinstall it into
the cluster?
Thanks in advance.
Markus

[Users] connecting to oVirt/RHEV VMs through proxy and the oVirt API
by i iordanov
Hello,
My apologies for cross-posting, but this discussion concerns both mailing
lists, I think.
In Opaque, I recently started setting the proxy property of SpiceSession
from a console file, as is done in remote-viewer, in order to support
installations where the nodes are not "visible" from the point of view of
the client.
However, then I remembered that I have not seen the proxy property being
available through the oVirt/RHEV API. I looked at the latest remote-viewer
code, and I looked through the oVirt/RHEV API documentation, and indeed, I
see no way to get proxy information other than through the console.vv file.
If I am correct, then this means that both Opaque and remote-viewer cannot
connect to VMs behind a proxy unless a console.vv file is used, which also
means that since console.vv files are unobtainable through the User Portal
on mobile devices, mobile devices effectively cannot at all connect to such
VMs if the user is not an Administrator.
Would it be possible to expose the proxy parameter through the API? I
couldn't find a bug opened about this, but it doesn't mean it isn't there
:).
Thanks!

NFS Storage domain backup
by Mohyedeen Nazzal
Hi ,
I'm using NFS storage domain, is it possible to backup the domain manually?
or is there an api in ovirt which support this?
For manual backup, is possible to use tools like rsync ? or the data will
not be consistent ?
Any idea of possible solutions for this?;as we don't have dedicated storage
box.
Thanks,
Mohyedeen.

Hosted-Engine HA problem

Hi Guys,
I need help with my ovirt Hosted-Engine HA setup. I am running on 2 ovirt hosts and 2 gluster nodes with replicated volumes. i already have VMs running on my hosts and they can migrate normally once i for example power off the host that they are running on. the problem is that the engine can't migrate once i switch off the host that hosts the engine.
oVirt 3.4.3-1.el6
KVM 0.12.1.2 - 2.415.el6_5.10
LIBVIRT libvirt-0.10.2-29.el6_5.9
VDSM vdsm-4.14.17-0.el6
right now, i have this result from hosted-engine --vm-status.
