(This usually reserved for the Enterprise versions of Windows Server 2K8 and 2K12) You'll need to change the line from -smp 6,sockets=6,cores=1,threads=1 to -smp 6,sockets=1,cores=6,threads=1 (or cores=2,threads=2, if you want to emulate a dual core / quad thread CPU). - Gilboa -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
