Well, we want send a request to the guest to shutdown and poweroff the device. > Why don't you just trigger surprise-removal from outside the guest? To give the guest a chance to shutdown the device gracefully? Umount filesystems, flush data to disk. Also guest stability. Traditionally linux isn't very good at dealing with surprise removal, although the situation is improving. Emulating surprise-removal has been discussed too. More as fallback in case the guest doesn't respond to the attention button. Right now we don't have it but should be doable. For some kinds of devices it shouldn't be a problem to go straight to surprise-removal. I'll go experiment with that. take care, Gerd
