Just a quick feedback: Interrupts of the root cell (the Linux that hands
over the control to the hypervisor) get stuck when starting Jailhouse.

What basically happens there is that Linux boots up with DMAR off but IR
on, then Jailhouse takes over, turning IR off for a moment, reconfigures
things so that it gains control, and then reenables IR (and also turns
on DMAR). After that, interrupts no longer arrive at that guest, which
is now L2.
