xl vcpu-set with a HVM domU sends an ACPI event to do hot-add of cpus. But if the vcpu count is decreased the domU does not offline any cpu. So far the only way to enforce offlining is to process the output of 'xenstore-watch cpu'.

Why is HVM excluded in drivers/xen/cpu_hotplug.c:setup_vcpu_hotplug_event()? I think that would be the place to receive notifications from xenstore about cpus being offlined/onlined. Olaf
