<p>Hi,</p>
<p>Thanks a lot for having a look.<br>
</p>
<p>HA VMs were migrated, non HA vms were turned off, syslogs were
not saying anything useful, dmesg reported graceful reboot.</p>
<p>What errors are indicating? may be there is a useful hint to
proceed in investigation?</p>
<p>Thanks in advance again</p>
<p>Cheers</p>
