There's nothing wrong with what the command line set here. It is simply configuring 2 vCPUS where each vCPU is represented as a separate socket to the guest, rather than what you describe which would be 1 socket with dual-cores. You don't mention what Windows version you are using, but some versions are not clever enough to switch between a uniprocessor config and SMP config. So if you installed those versions on a 1 CPU guest, then even if you later boot the image on 1 CPU guest, it won't see the extra CPUs. There are hacks you can do to "upgrade" a windows install from the uniprocessor to multiprocessor HAL - see the microsoft kbase for more info Regards, Daniel -- |: http://berrange.com -o- http://www.flickr.com/photos/dberrange/ :| |: http://libvirt.org -o- http://virt-manager.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: http://entangle-photo.org -o- http://live.gnome.org/gtk-vnc :| _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
