Re: [Xen-devel] HVM resumable with -c flag?

["Mike Sun" <msun@xxxxxxxxxx>]

Thanks Keir.  It is the qemu-dm.  Hmm, not my dilemma is whether it'd
be a fairly easy thing to incorporate the newer qemu-dm into a 3.1.x
branch...  I've made some major changes to the shadow page table code
for my work and would rather not try and merge them into 3.2.x if I
don't have to at this point.
