Thanks. I'll try this. However I am still interested in kvm exit on
behalf of the guest system w/o acpi. I experiment with running KVM in
X window environment (window manager runs on the virtual machine, not
on host). At the moment the guest OS shuts down, console window may
lose focus, and since window manager has already been killed by OS
shutdown, the console window may not be accessible for keyboard input.
To fix this, I patched evilwm (the simpliest window manager
available): when kvm process exits, its parent shell script sends
evilwm a signal, and it restarts. Thus window management will be
restored. But kvm should exit.

In general, it would be a useful option if qemu monitor was accessible
from within the guest OS as some virtual character device where
commands might be written. Unfortunately I couldn't find anything like
this in QEMU documentation.

PS How does the -no-reboot option work?

I never was able to actually _reboot_ an OS in kvm - it just hangs.

Thanks.
