Hi,
as you know Solaris (Open Indiana) has qemu-kvm although they don't use libvirt (in fact libvirt tighted to much to Linux specifics).
If vdsm whould interact with qemu-kvm without libvirt it would open a way to have Solaris hosts in ovirt-engine.
libvirt is another abstraction after vdsm layer, or if vdsm could use "plugins" to interact with qemu-kvm (libvirt, "native", solaris-style), it could use current mode, bypass libvirt and use solaris tools to talk to their qemu-kvm.
In the old days, vdsm used to work with qemu processes directly. We moved to be using libvirt's abstraction in order to gain then-new qmp code "for free", and to make it easier for 3rd party applications poll oVirt VMs over the libvirt api. We also use the libvirt dom xml as an API for vdsm extension hooks. Beyond that, there are a few Linuxisms in Vdsm itself. I would first want to see it ported to non-Fedora-flavor Linuxes (did someone say Ubuntu?), and only later to Solaris. Dan.
