But the problem actually has nothing to do with ACPI -- it's the PV

I'm puzzled as to why you say that as the problem does not appear
without ACPI in the xl.conf file.

I can still get the same effect -- the only difference for me seems to be that the "window" in which I can send a shutdown with no effect it is shorter. Maybe ACPI causes the extra few seconds at boot which makes it more likely you're going to hit it?
