Re: [libvirt] [PATCH] add nested HVM to libxl
I agree that it needs to be done the right way.
I am willing to help where I can but my basic knowledge of the code is
badly lacking so there is no reasonable way for me to contribute in a
significant way.
I am ok keeping my own hacks to the code that let me work along on my
projects and hope that some day this will get fixed.

Yep, I can certainly understand that POV. Unfortunately I think in this
case we really do need to do it the right way. IIUC, Xen does indeed allow
the CPUID mask to be configured, so it ought to be possible to map from
the libvirt XML to the CPUID mask format. It would certainly be a non-negligble
bit of work though.
