Bug description:
  [Impact]
  Users won't be able to run a Linux inside a Linux guest.

  [Test case]
  Launch an L1 guest with libvirt, then launch an L2 guest using qemu inside 
that first/L1 guest.

  [Potential regression]
  There might be reduced performance due to vmexits for interrupt handling.
