[ops][victoria][cinder] Import volume?

I've been successful at the tasks listed below, but the resulting volumes don't boot.  They stop early in the boot process indicating the root partition cannot be found.

I suspect the issue is with either the disk UUID links, or with partition detection.

When running the VMs under XenServer, we have /dev/disk/by-uuid/<UUID> --> /dev/xvda#

Are these created dynamically by the kernel, or are they static soft-links?

Can I get away with adjusting fstab to use what the partitions are likely to be after transition to OpenStac?  Are these of this form: /dev/vda#?

Thank you,

Here is the documentation for that command:


Also note, if you no longer need to manage the volume in Cinder, but you do not
want it to be deleted from your storage backend, there is also the inverse
command of `cinder unmanage`. Details for that command can be found here:
