Hello,

I googled for xen Hybrid, but have question if I understand it correct. 
Now the Dom0 is a PV Guest. With Xen Hybrid the Dom0 can run as a HVM 
with PV features on the hypervisor. This would make it possible because 
of nested virtualization that KVM and VirtualBox run inside dom0 right?

And my second question would be: Is the aim of Xen hybrid to bring Dom0 
support to more OSes?

Best Regards
