[Xen-devel] Status of nestedhvm (on Intel)

[Christian Tramnitz <chris.ace@xxxxxxx>]

May I ask what the current nestedhvm status in Xen 4.1 is? The parameter exists,
the documentation just says that only previously existent cpu features will be
passed through, but I can't seem to get a VM with "vmx" (for testing of ESX or
Hyper-V in a Xen domU) working. "nestedhvm=1" seems just to be ignored...

Is this AMD-only in 4.1? Are additional CPU host features required to make this
work (like EPT, which I do have on this Xeon 5520 box or "Shared EPT" that I
dont have but could be AMD related anyway)? Do I need unstable to make use of 
it?


Thanks,
   Christian
