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
