Hello: I'm developing a fault tolerance system, and I'm trying to use save/restore operation. But it's working fine when I restore the file saved on the same guest, but If I move it to another host, and then try to restore using the file previously saved I got this error. I ask for help to know if this kind of operation is allows, and if it is, how can I do to work it. The exactly sequence using virsh I've test is: On [HOST1]: Using virsh 1) save [domain] [file] 2) restore file 3) destroy [domain] On [HOST1] using ubuntu sh 4) cp [guest.img] [guest.xml] [file] to HOST2 On [HOST2] using virsh 5) define [guest.xml] (using image on destination in HOST2) 6) restore [file] The restore troughs the following message: <div style="margin-left: 40px;">virsh # restore sv-chubut-2011-04-01-09:58 error: Failed to restore domain from sv-chubut-2011-04-01-09:58 error: monitor socket did not show up.: Connection refused </div> Thank you very much.
