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 Enrico |

Hi. The command run when cad is hit is handled by /etc/inittab. Change the guest /etc/inittab entry for cad from shutdown -r (for reboot) to shutdown -h (for halt, rather than reboot). um...@vi... wrote: > 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 > > Enrico > > > |

I've posted an init script some while ago. You need the above uml modifications too. It sends cad to the uml running in a "screen" and then waits until the uml process returns. This way no filesystem corruption can occur. However there may be problems when anuml hangs on shutdown. Would be a good idea to add a hard kill after some minutes to the script.

I have set my UMLs up to have Control+Alt+Delete to be 'shutdown -h now'. I then have a script that, when I exectute a shutdown, first does a 'uml_mconsole $UML' cad for every running guest and then waits for 60 seconds. After 60 seconds, it looks for any remaining running UMLs and, if any remain, waiting another 60 seconds. If after 2 minutes some are still running, that means they are hung and I reboot anyway. Works pretty good, shutdowns take a bit, but I dont have to spend much time in fsck. Jason The place where you made your stand never mattered. Only that you were there... And still on your feet.
