If you are using 4.10, we do support migrations when a VM is in unknown (i.e. hypervisor is down) provided there is a shared storage. Next release (4.12) will include the ability to migrate in poweroff.<div><br></div><div>Meanwhile a work around, (there are two actually fake a hypervisor failure to get the VM in unknown and use the previous feature or fake a migration failure).</div><div><br></div><div>I've not tested this myself so watch out:</div><div><br></div><div>1.- Update the kvm migrate script by adding at the very beginning something like:</div><div><br></div><div>sleep 600</div><div>return</div><div><br></div><div>We want to get the VM in MIGRATE state for a while </div><div><br></div><div>2.- Manually move the VM: Go to the hypervisor, and shut it down (i.e. virsh...); move the config files (those in ssh system datastore); got to the other hypervisor and manually create the VM.</div><div><br></div><div>3.- use onevm recover <vmid> success, the VM should become running in the new host.

<br>
Is there a way to move a VM from one host to an other when migrate/live<br>
migrate fails.<br>
<br>
We are using ceph as backend and have ssh systemstore.<br>
<br>
A process like<br>
1 poweroff VM<br>
2 Move the configs<br>
3 -- I guess that we should do some manual db changes --<br>
4 poweron machine on new host<br>
<br>
Any comments would be great.<br>
<br>
Thanks,<br>
