No, ACPI hotplug code is not involved in pv domains' vCPU adding or removal. Instead, the pv kernels create a xenstore watch on their domain's "cpu" node, reading cpu/<id>/availability when the watch fires. See drivers/xen/core/cpu_hotplug.c (for the forward ported kernels) or drivers/xen/cpu_hotplug.c (for the pv-ops ones).
