Description of problem: XEN DOM0 kernel does not detect all 4 processors in my system. If I run "xm vcpu-set 0 4" it causes a crash and a system freeze. Version-Release number of selected component (if applicable): 2.6.20-2925.5.fc7xen How reproducible: 1. Boot 2.6.20-2925.5.fc7xen with xen on a multi-processor system 2. To duplicate crash, run "xm vcpu-set 0 2" Actual results: Kernel sees a single processor Expected results: Kernel sees four processors (or however many are present) Additional info: DMESG and crash message from attempted "xm vcpu-set 0 4" attached

This has been fixed in BZ 238015 (there are a couple patches in that BZ if you are eager to test it out), just hasn't made it into latest rawhide yet. I hadn't tested vcpu-set when I fixed SMP, but I'm sure it's from the same source issue...Yes, just tested and vcpu-set works as expected in a fixed kernel.
