RE: [Xen-devel] Use paravirtualized kernel with HVM-image?

["Tian, Kevin" <kevin.tian@xxxxxxxxx>]

It's similar to what Jun Nakajima proposed as hybrid virtualization:
http://ols.108.redhat.com/2007/Reprints/nakajima-Reprint.pdf

However it's not a simple replace-with-pv-kernel action, since pv
kernel and unmodified linux kernel expects different low level interfaces

Thanks,
Kevin
