I just submitted this fedora bug with lots of details: https://bugzilla.redhat.com/show_bug.cgi?id=555788 It sure seems to me like the contents of the debug address trap registers are leaking across virtual machines (at least for opterons on this motherboard :-). Anyone seen anything like this before? (I've been having similar problems on this host since it was running xen 3.1 before switching to kvm). -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
