I've realized that both reports of this errors were from hardware that
supported posted interrupts, while I don't have any hardware that
supports it. The following is just a hunch, but could you try the
attached patch?
I'm also working on a patch to check what actually caused vmlaunch to
fail, but that's going to take a little bit more time.
Roger.
