The new API should definitely have a 'flags' argument although it may be unused for now.
As an additional thought. Isn't this possible with the existing virDomainSendKey API? The sysrq combination is a key code, so you should be able to use that API to do the same thing. In that case all you need is a virsh wrapper and an implementation of the API for the XEN driver. Peter
