Raw is probably universally supported (although in my own experience, I can only state that for xen, qemu, and lxc). Other formats are driver dependent (qemu probably supports the most formats). There is talk upstream on the qemu list of creating a libqblock library that would make it easier to expose any disk format that qemu understands into an NBD drive, so that other hypervisors need only learn NBD to get the benefit of all sorts of underlying formats, but that's still a ways out. It would be nice if querying hypervisor capabilities included a list of which disk formats that hypervisor understands; but someone would have to write patches along those lines. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
