Hi,<div><br></div><div>There are basically two options:</div><div><br></div><div>1.- Recover from outside: this means logging in the hosts and perform any recovery actions needed to boot the VMs again</div><div><br></div><div>
2.- Restart. When a VM is in unknown state and if the remote VM_DIR is in place (i.e. disks files or devices are in the cluster node). The restart action will issue a boot action.</div><div><br></div><div>So in your case I think it is worth trying onevm restart .</div>

<br>
A few days ago we experienced a major power outage taking out our entire opennebula cloud. Nothing shut down cleanly and when the headnode came back online, it still thought the VMs were running albeit in an "unknown" state. Of course, the images were still on the host nodes...<br>
<br>
Is there a way to recover *nicely* from such a situation without redeploying all the VMs and getting back most if not all of the data on the VMs?<br>
<br>
Thanks,<br>
Dan<br>
