I thought I replied to this one, but I dont' see my email... So, from CEPH/NFS to SolidFire should work (in this direction only) - or let me say "used to work" (haven't tested it recently) - this was developed for my ex-company where I use to work, by Mike Tutkowski from NetApp) Also, my understanding is that it's also possible to migrate VMs using local storage from host to host (whole VM with its disks) - @Gabriel Beims Bräscher <[email protected]> can confirm this, afaik?
If you are using Ubuntu - all fine - qemu-kvm supports live storage migrations from Ubuntu 14.04 at least, an onwards. If you are using CentOS 7, you have to use qemu-kvm-ev from the oVirt repo ONLY - all other versions of qemu-kvm do NOT support storage live migration (Redhat revoked it for $$$ reasons, while it was working fine in CentOS6) If your tested it and it worked from Gluster to NFS - that's (great) news (for me).
