The only way to find out if CPU hotplug is really available on a given machine-type is by actually trying to run cpu-add, right? Is this sufficient for libvirt requirements?
As long as the command fails when it's not supported it's okay. (cpu_set HMP command does not fail when offlining a cpu even if it isn't supported and that's real pain to use) Peter
