Description of problem: The current implementation has a popup to ask "are you sure" (yes/no) when you select doing a shutdown:force-off (virtual poweroff). This is OK for something which occurs infrequently. However, when this is used a lot, it becomes more than bothersome!! [think pain in the ...] Ideally, there should be some global setting which can be set/reset instead of just a check-box on the dialog which, if un-checked, will result in the popup never occurring again.
After thinking about this RFE, I believe that having the option on a per guest basis may be better. Regardless, if the popup can be turned off, there should be a way to turn it back on without vi'ing an xml file.
Moving upstream, but personally I think the dialog makes sense and anyone who really needs to do this that much can just use 'virsh destroy'
Numerous people have asked for this, so I've implemented this upstream: http://hg.fedorahosted.org/hg/virt-manager/rev/958d7ff99a5b Closing as UPSTREAM.
