Subject: paravirtops kernel and HVM guests

Jeremy,
  I was trying the latest bits from your paravirtops tree with
xen-unstable. Dom0 is booting fine in Fedora 10 environment. I am seeing
page fault handing error while trying to create an HVM guest. 
Is anybody working on the HVM support on top of paravirtops kernel?
