You can add "seize=1" to your pci string to have xl automatically do both steps for you. Obviously, use this with care. :-) More on your next post... -George _______________________________________________ CentOS-virt mailing list CentOS-virt@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos-virt
