I think this will not be trouble in test with current implementation, but it's buggy as firmware. - But - ACPI firmware which doesn't support memory hotplug is not tend to have memory object. Usual people who needs emulation will not need to remove something. Thanks, I'll discuss with Goto-san and update lhms page. -Kame
