Thank you ;-)

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...

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.
