[Qemu-devel] [PATCH] new SDL keyboard shortcuts to start and stop VM

[Mulyadi Santosa]

IMO, it would be faster if we provide keyboard shortcuts that will
stop and resume VM execution right from SDL guest interface, rather
than switching to console monitor first and type "s" or "c"
respectively.

Note: I simply skip checking the keys in encrypted block devices when
resuming the VM. Not sure whether we really need it or not.
