we need logs to do anything about it. Engine log and the corresponding vdsm.log from each host

Comment 3 Michal Skrivanek 2013-07-03 05:00:56 UTC
and the vdsm logs from hosts please
also - is/was the guest agent installed in those guests?

Comment 8 Michal Skrivanek 2013-07-04 06:06:19 UTC
Thanks. a bit clearer now. Now libvirt log please:)
so far what seems to be happening:
- VMs started to be migrated away correctly
- They almost finished, but before the end of migration the progress gets stuck
- After 300s we try to abort the migration but libvirt doesn't seem to abort the job
- After another few minutes libvirt reports migration was successful and VMs are resumed on destination
- reboot happens but it doesn't seem to be initiated from vdsm, rather from within the guest. Or the whole migration process got weird - so we need libvirt logs and qemu logs if possible as well

Comment 12 Michal Skrivanek 2013-07-12 10:09:11 UTC
libvirt logs are missing from the time of starting the migration, nevertheless, the qemuMonitorEmitReset suggests the reset happened at QEMU level after ~500ms after the migration finished.

so...either guest triggered that or maybe QEMU logs will help

unfortunately the libvirt log is from a different month.
Can someone please post set of logs from engine,vdsm,libvirt and qemu from the same time from both src and dst sides? I find hard to correlate it from what is attached in the ticket.
Thanks

Yoshinori, can you follow up with the above request from Michal if possible.
