Instead of having the guest teardown all these bits of  setup.  I think 
it would be preferable to have the toolstack build a new domain with the 
same memory contents from the original VM.  The toolstack would then 
start this new domain at the kexec entry point.

The advantage of this is you don't need to add new hypercall sub-ops to 
teardown all bits and pieces, both for existing stuff and for anything 
new that might be added.
