<p>Hi,</p>
<p>The migration is working fine with Cluster Switch set to "Legacy"
Mode.<br>
</p>
<div>
<p style="margin-bottom:0cm">But I have run into a different
problem. Yesterday, for some reason, I had to restart the hosts.
But the Hosts never came online. Hosts were constantly in Non
Responsive state. I manually fenced it, and Vds command timed
out.</p>
<p style="margin-bottom:0cm">I found that NIC was down for some
reason. I brought it up and again fenced the hosts. Again the
Vds command timed out. I manually attempted to restart the VDSM
service, but host reported there is no such service. Starting
VDSMD service resulted in failure. <br>
</p>
<p style="margin-bottom:0cm">Finally, I had to forcefully remove
the hosts, reinstalled base (CentOS 7) on hosts and re-added
them to oVirt with the storage domain intact. All hosts, storage
domains went online and all VMs were intact.</p>
<p style="margin-bottom:0cm">Post reinstallation, I set the
Cluster Switch mode to "Legacy" and tried migration and it
worked fine.<br>
</p>
<p style="margin-bottom:0cm">I fail to understand what went wrong
while rebooting the hosts.<br>
