Re: [Xen-devel] Xen inside Xen with VMX?
Current VT implementations do not have this ability, AFAIK.

Hello,
out of curiosity, I was wondering if it is possible to support
recursive emulation in Xen, i.e. if it is possible to have Xen as a
guest in Xen (possibly with other guests inside those Xen's)? I'm
particularly curious if this is possible when running Xen using Intel's
VT extensions (or AMD's Pacifica), i.e. do these enhancements provide
the hypervisor with enough control that it can virtualize the
virtualization enhancements themselves (without a prohibitive loss in
performance)?
If it's not possible I guess VT etc. doesn't really offer true
emulation since the guest would be able to detect the emulation by
noticing that it wasn't itself able to become a hypervisor.
Thank you in advance!
Best regards,
MH
