On second look at the vdsm.log I see that disk preparation in the
destination host failed (timed out), try to take a look at
vdsm.log at the destination.
In addition, for some reason getVmStats returns "Virtual machine
does not exist" right before the migration.

Thanks,
Rami Vaknin, QE @ Red Hat, TLV, IL.
The vdsm log is already included earlier in the conversation;
http://pastebin.com/BEeqFCCb
I don't really know where to go from here. :/
The exact issue that caused the prepareVolume to fail is not mentioned
in the attached log.
Can you please tell whether the attached vdsm log is from the migration
source host or from the migration destination host, and attach as well
the second missing log? The vdsm log from the host where the vm should
run after the migration should contain a failed/hanged lvm command on
the vm's disk.

There is no problem

anything like that.
If I shut<br>
down the vm I can
start it on the

Do I need to do
something to make
live migration work?
Trying to dig in<br>

there's so much

Here is the failure, "code 9" is not

Domain in libvirt is simply a vm.

<div>Alright, so what does this mean then? The machine
I'm migrating to can't see the vm?<br>
That doesn't make sense since I can manually start
it on that host..</div>

On second look at the vdsm.log I see that disk preparation
in the destination host failed (timed out), try to take a
look at vdsm.log at the destination.<br>
In addition, for some reason getVmStats returns "Virtual
machine does not exist" right before the migration.<br>

<br>
The exact issue that caused the prepareVolume to fail is not
mentioned in the attached log.<br>
<br>
Can you please tell whether the attached vdsm log is from the
migration source host or from the migration destination host, and
attach as well the second missing log? The vdsm log from the host
where the vm should run after the migration should contain a
failed/hanged lvm command on the vm's disk.<br>
