<div>I know that using block storage like Cinder you can evacuate instances from hosts, but in my case we are not yet using Cinder or other block storage solutions, we rely on local ephemeral storage, configured on using LVM</div>

<div>Is it possible to evacuate (migrate) ephemeral instances from compute hosts and if so does any one have any experience with that?</div>

<div>Hi Davíð</div>
<div><br>
</div>
<div>Have you actually tried the regular "nova migrate UUID" option? It does copy the entire disk to a different compute - but i'm not sure if it's working with LVM. I've also used [1] ("nova live-migrate --block-migrate UUID") in the past - but unfortunately
this also wasn't LVM backed ephemeral storage.</div>
