Welcome David,
Thank you ;-)
We find it sufficiently advanced, since 3.5 is nearing release most of
our wishlist has been taken care off ;-)
Check out the case stories like
(http://www.ovirt.org/Brussels_Airport_Case_Study)
Yes, it is an interesting article even if I did not understand the
Openstack point because, if I'm not wrong, Openstack can run over any
virtualization solution, VMware, KVM, etc...

Ovirt engine is the management part (like vCenter), there is no need
for it to be that optimized as it's not running VM's itself.
Yes, I saw my mistake between oVirt engine and oVirt node ;-)
My really question was : is it a good idea to run the oVirt node over
another OS ? It would be more performant to run the oVirt node directly
over the hardware, like ESXi...
May be it is in the roadmap ?
And I have another question : is there something like VMFS to store the
VM in the SAN ? It's more performant to use FC than NFS shares...
Thank you.
David.
What you're talking about is ovirt node:
