Hi,this is patch to add maxvcpus support to xen xm command. It's using vcpu_avail bitmask and sets the number of vcpus to maxvcpus if present. If it's not present, old behavior is preserved. In domain config file you can define it as follows: maxvcpus = 4 vcpus = 2this automatically sets vcpus to 4 and corresponding bitmask to present 2 vcpus in the guest with option to increase it up to 4 vcpus. If maxvcpus is not present, the old behavior for vcpus is preserved. Thanks, Michal
