So just to clarify: the native driver for another hypervisor (bhyve)
would not be accepted into Nova even if it met testing coverage
criteria? As I said the libvirt route is an option we consider, but we
would like to have the possibility of a native FreeBSD api integration
as well, similar to what you can have for non-libvirt hypervisor apis
available already in Nova.
