<p>Hi,</p>
<p> I have installed latest upstream master on RHEL7.2. When i
try to put a host in maintenance which runs HE vm i see that vm
does not get migrated to another host and host is stuck in
"preparing for maintenace" state. I see the following errors in
the vdsm.log . Can you please help me understand why this error is
seen? <br>
</p>
