Hello Andrija.
Gluster as primary storage works fine. Storage migration, with powered
off VM's, it's working too. My problem is just doing this with VM's
running.
I'm using Ubuntu 20.02, CentOS 7 and Windows 10 and 2016 for testing and
not working.
But it is the life, thaks all
Best regards,

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:[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).
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.
