@mhhajeer SendCtrlAltDel works by sending keyboard events (i.e. key presses) to the guest. Keyboard events in the guest are handled by the keyboard driver. That means you need a guest kernel with the i8042 and atkbd drivers. One such kernel is used by our integration tests.

Check out the docs section for more details.
