Chapter 24. Feature support and limitations in RHEL 9 virtualization

Describe the issue:

The note reads:

Storage live migration
Migrating a disk image of a running VM between hosts is not supported in RHEL 9.

The word hosts above makes this very confusing. As VM live migration is between hosts, but Storage Live Migration the VM stays on the same hosts and only the disk moves from one backend to another. So its not very clear what this is really about.

Impact of this issue:

Potential misunderstanding of the support status of --copy-storage-all (documented in Chapter 12) which is used with VM live migrations (copy disk together with VM when live migrating the VM from Host A to B) with disk only storage live migration (i.e. move disk from NFS server A to NFS server B with the VM up on Host A).

Suggestions for improvement:

Make it clearer what is not supported.
