I see. Yes, that works for PPC Book3S too. We check for signals on the beginning of vcpu_run. I'm not sure about BookE though. Either way - wouldn't it make more sense to just move the check to generic code?
Well, the check happens very deep in x86 code (vcpu_enter_guest(), during the critical section switching into guest mode). It should be possible to refactor it into a skeleton that does this (and checks vcpu->requests etc.) and calls arch code to do the actual work. A small gain for a lot of churn, but maybe worthwhile.
