I'm having an odd issue that i find hard to believe could be a bug,
and not some kind of user error, but im at a loss for where else to
look.

when booting a linux ISO with QXL SPICE graphics, the boot hangs as
soon as kernel modesetting kicks in. Tried with latest debian, fedora,
and centos. Sometimes it randomly works, but most often it does not.
QXL / VGA VNC work fine. However if i wait a few minutes after
starting the VM for the graphics to start, then there are no issues
and i can install as usual.

So after install, i reboot, hangs on reboot right after graphics
switch back to text mode with QXL SPICE, not with VNC. So i force
power off, reboot, and wait a while for it to boot. If i did text only
install, when i open a spice console it will hang after typing a few
characters. If i did a graphical install then as long as i waited long
enough for X to start, then it works perfectly fine.

I tried to capture some logs, but since the whole guest OS hangs it's
rather hard to pull off. I did see an occasional error about the mouse
driver, so that's really all i have to go on.

As for the spice client, im using virt-viewer on windows 10 x64, tried
various versions of virt-viewer just to be sure, no change. I also
have a large amount on windows guests with QXL SPICE. These all work
with no issue. Having guest agent installed in the linux guest seems
to make no difference.

There are no out of the ordinary logs on the VDSM hosts, but i can
provide anything you may need. It's not specific to any one host, i
have 10 VM hosts in the cluster, they all do. They are westmere boxes
if that makes a difference.

Any ideas on how i should approach this? VNC works well enough for
text only linux guest, but not being able to reboot my GUI linux
guests without also closing my spice connection is a small pain.


as far as ovirt versions im on the latest, this is a rather fresh
install. just set it up a few days ago, but i've been a long time
ovirt user. I am using a squid spice proxy if that makes a difference.

I managed to extract a log file from a debian guest.
