Thank you.
This would make a great feature (and I'd add Linux container to the list), but
it's an expensive one. Introducing it into vdsm is a challange. But the complex
part is maintaining and testing it for years to come.
Personally, I'd prefer to focus on KVM. Higer in my portability wishlist are
non-Fedora distribution and non-x86_64 cpus. However if someone volunteers to
port vdsm to another technology (and maintain the code so that it does not
rot), I would be delighted.

I agree that it is unfortunate that we have limited the power of libvirt
in terms of the number of backends it can manage when integrating it
into oVirt.**Extending to VirtualBox would be an interesting project,
but I'm not sure how valuable it would be. As a long-time user of
VirtualBox I found it to be slower than KVM. I guess it could allow
people to use non-Linux Nodes. Like Dan said, a lot of work there so the
payoff would have to be big enough to justify it.
On the other hand, I think it would have far greater impact in terms of
number of use cases/users if we expanded VDSM to manage VMware ESX.
VMware is still arguably the market leader for virtualization. At the
very least, this would then provide a migration path for anybody wanting
to move away from VMware to oVirt (or, perhaps, visa-versa if we don't
do a good enough job with oVirt ;). Since the Nodes would effectively
still be restricted to Linux the task should be easier than e.g.
supporting a Node consisting of Windows+VirtualBox. As with VirtualBox,
there's no SPICE capability for VMware, so in addition to the VDSM work
the User Portal should be extended to support e.g. VMware Horizon View
Client.
-Bob
P.S. If we *did* support VirtualBox, the User Portal should be extended
to broker VNC connections since that's one way to connect to a console
with VBox. That wouldn't be a bad project in itself, and would have
value even without VirtualBox.
