<p>Hi,</p>
<p>The migration is working fine with Cluster Switch set
to "Legacy" Mode.<br>

<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 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>

the Cluster Switch mode to "Legacy" and tried
migration and it worked fine.<br>
