[uml-user] Best way to reboot multi guest server

[<um...@vi...>]

Hi, i have Fedora core 2 Host ( 2.6.9 + skas3-v7 )
with many Guests ( Kernel 2.6.9 bb4 ).

What is the best way to do a mass shutdown of all Guests?
I ask it because now i can't shut own my Host server wthout
a mass corruption of Guests FS.

( I have think about a mconsole with cad command but it reboot the guest =
..
i need a shutdown command )

Thanks
