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 <mailto:gabrasc...@gmail.com> 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).
Hope that helps,
Cheers,

Aha, you mean live storage migration between different types
of primary
storage.
That is indeed not supported with KVM and also not on the
roadmap at the
moment.
