I did a clean install and didn't change it over to StandardPC. The Control Panel says "ACPI Uniprocessor PC" or something like that (recalling from memory right now). As a third datapoint, I am seeing the TPR changing rapidly (which I would expect 0 changes if the ACPI stuff was disabled). > I noticed the kvm_stat below, there are no mmio exits. You need to > update the statistics. Yeah, this is fixed in my latest code which I will send out soon. I actually added a "light_mmio" and "apic_mmio" stat so we can tell the difference. I left mmio_exits to count the ones that go to userspace. ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
