Currently the two values are conflated. Then you can set max_vcpus as high as you like, but xenstore will tell the guest how many CPUs to bring up during boot. If we want a 'hard limit' check in Xen (kind of like we have a per-domain memory limit) to ensure that guests do not sneakily bring up CPUs that we didn't ask them to, then we can add that but it's an orthogonal change (i.e., different patch) to what you are trying to do here. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
