Startup/Shutdown scripts for KVM Machines in Debian (libvirt)

Hi,
I manage my KVM machines via libvirt and wonder if there are any init.d scripts for automatically starting up and shutting down virtual machines during boot/shutdown of the host?

Writing this for myself seems to be not that simple, as when shutting down, the system has somehow to wait until all machines are halted (not responding guests have to be destroyed etc.), and I don't really know how to accomplish this.

My host system is Debian Lenny, is there anything available? Perhaps libvirt offers something I'm unaware of?

Best Regards,
Hermann

I think it does. Copying the libvirt mailing list.

You can set it using "autostart" in virsh.

Hi,

in libvirt, there is two startup script you need to be aware. /etc/init.d/libvirt-bin for the libvirt daemon and the /etc/init.d/libvirt-guest for a properly startup/shutdown of the guests. And take a look at tht /etc/default/libvirt-*

Regards.
