You'd have to supply the callback that does this (it would be a security issue if a guest action could shut down the host by default, without the use of a callback installed specifically for this reason). Right now, this level of detail is not wired up. However, the callback signature does support a reason field, so you are welcome to write a libvirt patch that adds a new reason field and figures how to wire a guest recovery reboot into reporting a different reason than the default. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
