BTW, because I was in urgent need for virtual test environment for
Jailhouse, I hacked interrupt remapping on top of Le's patches:
http://git.kiszka.org/?p=qemu.git;a=shortlog;h=refs/heads/queues/vtd-intremap
The approach likely needs further discussions and refinements but it
already allows me to work on top with our hypervisor, and also Linux.
You can see from the last commit that Le's work made it pretty easy to
build this on top.
