     \begin{itemize}
       \item Splitting PV and HVM code:
-Refactor x86 hypervisor code. Make guest supporting code configurable via Kconfig.

       \item PV ABI in PVH container:
-Implement a PV ABI shim. Use it to translate PV hypercalls into PVH ones.

       \item Users can pick and choose the guest types
       \begin{itemize}
         \item Smaller binary, smaller attack surface
