"-action panic=poweroff" should be renamed to "-action panic=shutdown" on the command line. This is because "-action panic=poweroff" and "-action watchdog=poweroff" have slightly different semantics, the first does an unorderly exit while the second goes through qemu_cleanup(). With this change, -no-shutdown would not have to change "-action panic=pause" "pause", just like it does not have to change the reset action. "-action reboot=none" should be renamed to "-action reboot=reset". This should be self explanatory, since for example "-action panic=none" lets the guest proceed without taking any action.
