Hi David, thanks for your reply.

I don't really understand that:

If you do a xm shutdown <domU> then I'm quite sure that Xen does send
the right commands to a PV/HVM domU or is it in fact not something
FreeBSD specific and doesn't work for any guest OS on HVM domU?
I remember that i.e. the windows GPLPV drivers have a device driver
that is used to trigger the VM shutdown.

So I'd think this is an issue where I gotta do something on the domU side.

But maybe we're talking different things :))
