And I suppose we canalways stuff vmc[bs]->rip into regs->eip and pull it back out again when we get back - using a wrapper function may be the easiest way to achievethis (at least short term). Yes, I expect HVM users will want some kind of helpful wrapper around the core emulator. I'm trying to keep the emulator itself very generic, so it makes sense that some tailoring will be required in some usages. We will of course also need to get the communication with QEMU done in some way. Yes, I don't imagine that is hard as long as you're prepared to copy the guest's register state to and from qemu-dm. Even on x8664 it's only a couple hundred bytes so unlikely to be a significant overhead. Then you can simply have a copy of the emulator inside qemu-dm. -- Keir I haven't spent any time looking at it so far... _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
