Hello, I've just stumbled upon this assert while testing PVH on different hardware. It was added in 7c4870 as a safe belt, but it turns out INS and OUTS go through handle_mmio. So using this instructions from a PVH guest basically kills Xen.
I've removed it and everything seems fine, so I'm considering sending a patch for 4.5 in order to have it removed. I think the path that could trigger the crash because of the missing vioapic stuff is already guarded by the other chunk added in the same patch. Roger. _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel
