Hi,<div><br></div><div>1: Yes, onehost flush [1]</div><div>2: If the images are persistent, the VM will be using a link to the source image (unless you are using the ssh transfer manager driver), and the redeployed VM will be up to date. Volatile and non-persistent disks are lost on resubmit, but this can be changed following this workaround [2]</div>

What happens if a host goes down hard and the OS volume cannot be recovered, can the vms be restarted on another host without redeploying from the base image?</div>
