Open Stack

Dear Openstack community,

I have 1 physical node with x4 nvidia nv100 running 1 fat vm. Additionally I am adding a nvme drive into that host and I would like to attach the nvme drive to the vm. Ideally I prefer to avoid data migration and redeploy the software.

My problem is that I don't have another host with gpus so I am guessing that the vm can't be migrated. Am I right assuming this?

So far I thought about 2 possibilities but I don't know whether they would work:

Option 1: crate a new flavor with the pci device pass-through and resize existing vm (I hope the new vm with the new flavor will have the nvme attached).
Option 2: convert ephemeral virtual disk into a bootable volume. Destroy vm. Create new vm with the new volume as a boot device.

Which option would be preferred? Is there any other think I can do?

Thank you very much

Manuel
