How to expose NFS to create VM's across different compute nodes sharing the same NFS as a shared storage?

I have two compute nodes having their own ephemeral storage. I cannot live migrate the instance since I'm not using shared storage. How can NFS solve my issue as shared storage?

Try adding the NFS to the cinder service and try launching the Instance with Volumes created from cinder service.

Try mounting the nfs on both compute nodes OS and go into nova.conf and edit from state_path=/var/lib/nova to state_path=/yourmountpath/nova . Also create the folders inside /var/lib/nova into your /yourmountpath/nova aswell or nova will complain about some directories not existing. Also set the permissions and owner to the new path (owner is nova:nova i believe)
