A log will be nice.<br>
However, can you please compare /etc/vdsm/<a href="http://vdsm.id" rel="noreferrer" target="_blank">vdsm.id</a> in both hosts?<br>
If not available at new host it might be a bios issue, try to uuidgen > /etc/vdsm/<a href="http://vdsm.id" rel="noreferrer" target="_blank">vdsm.id</a> and add host.<br>
