From: Ross Lagerwall <[email protected]> When the guest writes to the RTC, the write is intercepted and emulated by Xen and the time difference is broadcasted as a TIMEOFFSET ioreq. Emit an RTC_CHANGE QMP event when this happens rather than ignoring it so that something can make use of the information (e.g. the toolstack can persist it between VM starts).
