I've heard that Christian had successfully updated qemu-dm to 0.7.0
and is working to update it to 0.8.1.  Is there anyway we can get
the (interim) patches from Christian ?  Is there a tree somewhere with
these patches ?

Leendert has asked me to look at the xen/qemu interface (e.g. a shared,
per-vcpu buffer that can be extended to contain hvm state) for this
'v2e' approach.  Leendert has given me details on his thinking, and I
am working on them right now.  However, this stuff is also dependent
on the updated qemu-dm from Christian (hence, my inquiry above).
Thanks.
