mmm... that is very interesting...
both vm's are identical? are they server or desktops type? created as
thin copy or clone? what storage type are you using? did you happen to
have an open monitor on the vm that failed migration?
I wonder if it can be sanlock lock on the source template but I can only
see this bug happening if the vm's are linked to the template
can you look at the sanlock log and see if there are any warning or errors?
All logs are in debug so I don't think we can get anything more from it
but I am adding Meital and Omer to this mail to help debug this -
perhaps they can think of something that can cause that from the trace.
This case is really interesting... sorry, probably not what you want to
hear... thanks for helping with this :)

Failed live migration is wider spread than these two VM's, but
they
are a good example because they were both built from the same template
and have no modifications after they were created. They were also
migrated one after the other, with one successfully migrating and the
other not.
Are there any increased logging levels that might help determine what
the issue is?

did you install these vm's from a cd? run it as run-once with a
special monitor?
try to think if there is anything different in the configuration
of these vm's from the other vm's that succeed to migrate?

Hi Dafna,
No snapshots of either of those VM's have been taken, and
there are no updates for any of those packages on EL 6.5.

does the vm that fails migration have a live snapshot?
if so how many snapshots does the vm have.
I think that there are newer packages of vdsm, libvirt and
qemu -
can you try to update

Do you have the same libvirt/vdsm/qemu on both

Please attach the libvirt and vm logs from both hosts.

I've attached the logs if anyone can help me track
