If you type "quit" or "reboot" at the loader prompt in the guest it
will exit with a non-zero exit code. You could modify the script that
launches the 'bhyveload' and 'bhyve' programs to quit if the exit code
is non-zero.

Something like this, perhaps:

while [ 1 ]; do
    # Launch the userboot loader
    bhyveload <args> ...
    if [ $? -ne 0 ]; then
        exit 1
    fi

    # Launch bhyve
    bhyve <args> ...
    if [ $? -ne 0 ]; then
       exit 1
    fi
done
