Hi Tino, and thanks for reply<br><br>I am still suffering this...and it's exactly as you said...from host A to B everything is OK, but if I try to restore the VM from B to A, (live)migration fails.<br>Sadly, I cannot see if I can migrate to C... we are using just few computer, two hosts and a PC without VT as frontend.<br>As soon as I can prove this (I need another machine with VTs, we are using KVM) I'll tell you.<br>Thanks again!!!<br><br>Daniele<br><br>> From: tinova@fdi.ucm.es<br>> Date: Mon, 21 Jun 2010 13:16:09 +0200<br>> Subject: Re: [one-users] Cannot suspend or migrate/livemigrate a VM<br>> To: daniele.fetoni@hotmail.it<br>> CC: users@lists.opennebula.org<br>> <br>> Hi Daniele,<br>> <br>> Are you still suffering this?
