Re: graceful shutdown from Virtualbox with NetBSD 5.x as a guest - with no network

I have a couple of NetBSD 5.2 servers running as VirtualBox guests
(OpenIndiana host). Every now and then (~every 2 weeks), the network
falls over and they lose their ethernet interfaces, as does the OI
server sometimes - the only way I've been able to get it going again
is to remove & replace a driver on the OI server and reboot everything
- normally this is just a minor PITA, but I am going overseas for
three weeks and won't be able to do it while I'm gone.
So, a Q&D hack - every night, reboot everything anyway and start the
VB guests from a script - it's ugly I know, but means at worst the
servers are down for 24 hrs.
For this to work, I need to gracefully shut down the NetBSD guests,
but when I run VB's acpipowerbutton from VBoxmanage it does a firm
kill - it doesn't seem to run the shutdown scripts that normally
happen when you shutdown a box. Running acpipowerbutton on the Linux
guests does the right thing, it takes them through a graceful
shutdown, but not so with NetBSD 5.2.x, AFAIK anyway.
Can anyone here suggest (or tell me what I'm doing wrong! And no, I'm
not getting off the OI server, ZFS is too big a win) how best to
gracefully shut down the NetBSD guests given that I have to assume
that the network is not available to connect? I can just do it from a
cronjob on the BSD boxes, but that's even clunkier.
Did you enable powerd?
If that doesn't work, a hack would be to use ssh to issue the shutdown.
You might want to use certificate based login into the root account and
setup sshd_config to use 'PermitRootLogin without-password'.
