Just trying to place in maintenance mode for a version upgrade, and<br>
one VM fails to migrate. The other 20-odd move over successfully. In<br>
/var/log/libvirt/qemu/, the VM's log on the source reports:<br>

On the destination host, it reports:<br>

[org.ovirt.engine.core.<wbr>vdsbroker.monitoring.<wbr>VmAnalyzer]<br>
(DefaultQuartzScheduler5) [f8aa18b3-97b9-48e2-a681-<wbr>cf3aaed330a5] VM<br>
'4921c5f5-7748-47eb-a90c-<wbr>8e9ecbd91bcf'(pete_win7) was unexpectedly<br>
detected as 'MigratingTo' on VDS<br>

<br>
<br>
It stays in 'preparing for maintenance mode' on the GUI for the host,<br>
and reports errors on the status pane below, but then it reports that<br>
the host has successfully been put into maintenance mode, even though<br>
the VM is still showing as in migration. After more time has elapsed,<br>
it reports a failure again, and then eventually the host will again<br>
report it is in maintenance mode, and so on.<br>
<br>
When I hit 'cancel migration' it reports that the migration has been<br>
successfully cancelled in the status pane at the bottom, but then<br>
shows it still in migration in the upper window. When I select the VM<br>
itself, it reports it is "Migrating From: 99%". If I cancel the<br>
migration here, it actually does cancel the migration properly.<br>
<br>
The VM itself is up and running ok.<br>
<br>
Version of oVirt is 4.1.0.4-1.el7<br>
<br>
Thanks in advance for any help. Please let me know if you need any full logs.<br>
<br>
Regards,<br>
