Hi all,

I have a bit of a problem - I have lots (>40) KVM machines with Ubuntu Lucid installed on my cluster. I am also a bit of a muppet system admin so I have to far too frequently reboot the hardware.

The problem is that the KVM guests with Ubuntu installed don't do anything when a shutdown request is issued. My Windows VMs shutdown fine - just, rather annoyingly and somewhat ironically (Windows behaving better than Linux!) not the KVM Ubuntu machines.

Does anybody know what is wrong? Is there a magic hook I need to enable in Ubuntu? These are all Ubuntu server editions by the way.

(The latest reason I had to reboot the hardware was because all three hosts were backing up the VMs to the SAN and the VMs live on the SAN. Network got swamped and lots of kernel exceptions in the VM log.)
 
You, my man, are a star! (even if you have a very specific definition of 'obvious' :)

kvm, virtualbox, vmware and any other virtualization software sends "shutdown requests" using standard ACPI method, it works exactly as it works with normal hardware, You need acpid to catch such signal and power down machine. There is nothing virtualization specyfic about that in proxmox.
