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.
