kvm my images no longer respond to shutdown. Is there a tweak which I
have missed?
virt-manager just invokes the shutdown API in libvirt, which has different
impls depending on the underlying hypervisor. In KVM case it invokes the
QEMU 'system_shutdown' command, which then triggers an ACPI power button
event in the guest. You need to make sure your guest has the <acpi/>
feature enabled in its XML config of course, and that the kernel has
activated ACPI (may need the acpi=force param), and that acpid is running.
IIRC certainly KVM versions have a bug wrt this causing it not to work
