[Xen-devel] libvirt and nestedhvm.

[Alvin Starr <alvin@xxxxxxxxxx>]

I am trying to shoehorn the ability to start a nested HVM into libvirt 
through the libxl interface.
Setting the nestedhvm flag is easy enough but I also need to mask the 
svm_npt cpuid flags.
This is where life gets interesting.

LIbvirt seems to probe the CPUID registers to determine what flags are 
available.
Libvirt then stops me from trying to mask the svm or npt flags since 
they are not visible in dom0.
So my question is.
Can I enable the svm,npt flags in dom0?
Is there anything equivalent to nestedhvm for dom0?

or is there a way to read the raw CPU flags?
