Hi,
During a discussion it was apparent some people expect the KVM guests to
be cleanly shut down when the host is being rebooted/shut down. Clearly
this is not done as part of the /etc/init.d/libvirtd sysv script stop.
So what likely is happening is that /etc/init/halt is sending TERM
signals to each remaining process, waits 5 seconds and then KILLs them.
Which would be fine if the kvm/qemu processes perform a shutdown on a
TERM signal _and_ they would in fact shut down cleanly within 5 seconds.
That's never going to happen. Five seconds is never enough.
A mechanism like the above would be very helpful in some situations. Has
this been discussed before, and should we ? :-)
Thanks for any insights !
Am I remembering correctly that the Xen way of doing things is to
freeze the guests?
