Hosts packages:

vdsm-4.14.6-0.el6.x86_64

libvirt-0.10.2-29.el6_5.7.x86_64

qemu-kvm-0.12.1.2-2.415.el6_5.8.x86_64 (from the jenkins build with live snapshot support)

Both those examples are of existing VM's, they were generated from a template, and they do have snapshots.

I just attempted to migrate another VM 'DHCP01' and it was successful, this VM was generated from the same template and containing snapshots.

I then was able to migrate the 'owncloud' vm successfully (which failed multiple times before), then I attempted another vm 'CV_Test' and it completed successfully but the time is way off, listing the migration was done in 31 seconds when the log shows 6 minutes. I ran through the same VM migration again to double check, and there was a kvm process for that VM running on both hosts for longer than what is listed in the GUI.

2014-Apr-29, 10:15 Migration completed (VM: CV_Test, Source: ovirt001, Destination: ovirt002, Duration: 31 sec).

2014-Apr-29, 10:09 Migration started (VM: CV_Test, Source: ovirt001, Destination: ovirt002, User: admin).

2014-Apr-29, 10:09 Migration completed (VM: central-syslog, Source: ovirt002, Destination: ovirt001, Duration: 26 sec).

2014-Apr-29, 10:09 Migration started (VM: central-syslog, Source: ovirt002, Destination: ovirt001, User: admin).

2014-Apr-29, 10:08 VM central-syslog started on Host ovirt002

2014-Apr-29, 10:08 User admin@internal is connected to VM central-syslog.

2014-Apr-29, 10:08 user admin initiated console session for VM central-syslog

2014-Apr-29, 10:07 VM central-syslog was started by admin (Host: ovirt002).

2014-Apr-29, 10:06 Migration completed (VM: owncloud, Source: ovirt002, Destination: ovirt001, Duration: 20 sec).

2014-Apr-29, 09:55 VM DHCP01 is down. Exit message: User shut down

2014-Apr-29, 09:55 Migration completed (VM: syslog, Source: ovirt002, Destination: ovirt001, Duration: 31 sec).

2014-Apr-29, 09:55 Migration started (VM: syslog, Source: ovirt002, Destination: ovirt001, User: admin).

2014-Apr-29, 09:54 VM shutdown initiated by admin on VM DHCP01 (Host: ovirt001).

2014-Apr-29, 09:54 Migration completed (VM: DHCP01, Source: ovirt002, Destination: ovirt001, Duration: 18 sec).

2014-Apr-29, 09:54 Migration started (VM: DHCP01, Source: ovirt002, Destination: ovirt001, User: admin).

Right now my greatest concern is a lack of consistency. I've attached vdsm/libvirt logs from both sides of the first migration error:

2014-Apr-28, 13:12 Migration failed due to Error: Fatal error during migration (VM: central-syslog, Source: ovirt002, Destination: ovirt001).

2014-Apr-28, 13:12 Migration failed due to Error: Fatal error during migration. Trying to migrate to another Host (VM: central-syslog, Source: ovirt002, Destination: ovirt001).

2014-Apr-28, 13:12 Migration started (VM: central-syslog, Source: ovirt002, Destination: ovirt001, User: admin).

Thanks,

Steve

Actually, the best way to debug this would be to look at both des and src vdsm logs.
is this happening on all vm's or just one of them?
was this vm launched from an iso? is that iso still available?
are there any snapshots?
what are the vdsm, libvirt and qemu versions?

Thanks.

Thanks, logs attached:

libvirtd.log.4/central-syslog.log covers the first event (17:12 timestamp)
libvirtd.log.3/owncloud.log covers the second event (01:22 timestamp)

Hi, in both cases the core issue is

ibvirtError: Unable to read from monitor: Connection reset by peer

can you share the libvirtd and qemu logs?

Hopefully we can find some more information on those logs.

Bests,
