oh, that's too bad ...
I do not understand something...
oVirt built on kvm
https://www.ovirt.org/documentation/introduction/about-ovirt/
Ceph, such as support kvm
http://docs.ceph.com/docs/master/architecture/
What could be the overhead costs and how big they are?
I do not understand why oVirt bad, and the qemu in the Openstack, it's good.
What can be read?
