There are a few ways:
        send a SIGTERM or SIGINT to the main UML pid from a different shell
        uml_mconsole <umid> halt
        uml_mconsole <umid> cad

They first two will do pretty much the same thing - shut down the
kernel with any regard to userspace, but it sounds like that's not an
issue here.  The third will activate C-A-D processing, which will
cause init to cleanly shut things down.
