Hi, I kinda vaguely remember seeing a patch while ago to support 128 physical cpus by hypervisor, I believe it was from Jan B. Now looking for it i''m unable to find it, i only see HVM vcpu patch for 128 vcpus in my search. Firstly, is it OK to increase NR_CPUS to 128, and secondly is it ok to do so in 3.4.3-rc2-pre tree, or is it 4.0 only? thanks much, mukesh _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
