Has anyone seen something along these lines or am I being to vague?

. The latter (spice) was a
little broken for me under Ubuntu, but I've used it on Gentoo without
issue so I figure this is more an Ubuntu thing than a non-RedHat thing.
If Red Hat were to pull an Oracle on us, it wouldn't do any good. Just
look where it got OpenOffice. :-)

CEPH, so that
the XenServer and VMWare's vm disk images are stored in ceph storage
over NFS?
Any reason why you'd go NFS? VMWare is capable of talking iSCSI to a
Ceph node running stgt.

I see mention of cache-tiers, but these will be at the wrong end of the

possibly changes to boot firmware settings and bootloaders too.
I'll look into a udev rule for our particular case and see how I go.

Yeah, in my case the OSD hosts are the MON hosts, and there was no such

time.

While 60MB/sec is getting respectable, doing so at the cost of data

In this topology though, I my only be using 256GB or 512GB SSDs, so much
less storage on SSDs than the HDDs which likely won't work that well for

Sounds like BlueStore may be worth a look once I move to Ceph v14 some
time in the future, which is eventually on my TO-DO list.
