I am thoroughly confused. Maybe that is because I have not been following 
this issue closely but it seems that you are using the paravirt interface 
as an API for Xen code in the guest? I thought the idea of paravirt was to 
have an API that is generic? This patchset seems to be mostly realizing 
Xen specific functionality? How does the code here interact with KVM, 
VMWare and other hypervisors?
  

For the most part, it doesn't disturb VMware or KVM.  Xen does need some 
additional functionality in paravirt-ops because they took a different 
design choice - direct page tables instead of shadow page tables.  This 
is where all the requirements for the new Xen paravirt-ops hooks come from.
