Maybe, I have solved my issue, but I still have one question.<br>Now I can migrate/livemigrate or suspend VMs, but I can do one of these operations just ONE TIME: if I migrate a VM, then re-migrate to the first host, I got error on qemu///session, because, qemu doesn't find the VM domain.<br><br>I wonder if this is normal, or I have still a problem. <br>If so, I'll report specific logs.<br><br>Thanks again<br><br>Daniele Fetoni <br><br><hr id="stopSpelling">From: daniele.fetoni@hotmail.it<br>To: users@lists.opennebula.org<br>Date: Fri, 18 Jun 2010 12:38:08 +0200<br>Subject: [one-users] Cannot suspend or migrate/livemigrate a VM<br><br>

<br>Hi<br><br>I'm using opennebula 1.4, qemu-kvm and a nfs shared folder.<br>When I try to suspend a VM previously created and working, or even if I try to migrate/livemigrate it, I obtain always the same error:<br><br>Fri Jun 18 12:23:03 2010 [LCM][I]: New VM state is BOOT<br>Fri Jun 18 12:23:03 2010 [VMM][I]: Generating deployment file: /srv/cloud/one/var/0/deployment.0<br>Fri Jun 18 12:23:04 2010 [LCM][I]: New VM state is RUNNING<br>Fri Jun 18 12:23:22 2010 [LCM][I]: New VM state is SAVE_SUSPEND<br>Fri Jun 18 12:23:23 2010 [VMM][I]: Command execution fail: 'touch /srv/cloud/one/var/0/images/checkpoint;virsh --connect qemu:///system save one-0 /srv/cloud/one/var/0/images/checkpoint'<br>Fri Jun 18 12:23:23 2010 [VMM][I]: STDERR follows.<br>Fri Jun 18 12:23:23 2010 [VMM][I]: error: Failed to save domain one-0 to /srv/cloud/one/var/0/images/checkpoint<br>Fri Jun 18 12:23:23 2010 [VMM][I]: error: operation failed: failed to create '/srv/cloud/one/var/0/images/checkpoint'<br>Fri Jun 18 12:23:23 2010 [VMM][I]: ExitCode: 1<br>Fri Jun 18 12:23:23 2010 [VMM][E]: Error saving VM state, -<br>Fri Jun 18 12:23:23 2010 [LCM][I]: Fail to save VM state.
