Wouldn't it be easier (and more efficient) to use TAP interfaces?
That's what I'm going to do as soon as I have time. (Well, Crossbow on Solaris instead of TAP but same idea)

I configured a Linux box to automatically fire up VirtualBox from rc.local, and then run a stripped down Linux instance in the VM to run SIMH-VAX.
Point being that I could then access the network interface of the SIMH-VAX from the host running VirtualBox :)
The host also ran decnet-linux..
It was quite nifty, but too heavy-weight for a Pi..

Hi Rob,
There may be a super easy way. Try the /etc/rc.local script file. You
can think of it in old MS-DOS/Amiga terms as the AUTOEXEC.BAT or
S:user-startup files. This script usually gets run after the system has
entered muti-user mode and after the networking is up and running. Have
a go running your simh VAX executable from there :)
You can also get fancy with GNU Screen so that it saves and disconnects
the console so you can connect to it after an auto-startup.

Subject: RE: [HECnet] Raspberry Pi + SIMH VAX?
I got my Raspberry Pi a few days ago too. I too have had few problems,
although for some reason the download of libpcap took an extraordinary
amount of time. I have built the 780 emulation, along with two
modifications
of my own, difference disk files, and a DMC11 emulation.
I am running the Pi now 24 hours a day as my HECnet router (node
VAX780 at
5.8) using the bridge running on a server that I already run 24 hours
a day.
The virtual disk files are stored on the server and I use SMB to
access them
from the Raspberry Pi, partly because the 8GB SD card I planned to use
did
not work and I had to use a 4GB one, partly because I have heard that
SD
performance is poor.
I am not as good on unix these days as I used to be, is there an easy
way to
get SIMH to start up automatically on booting the Pi?
I like the idea of a cluster of Pis, might get a few more at some
point and
try that myself.

Built
fine and runs perfectly.

on a
simulated 11/83 with 2048kW of RAM. I have DECNet 4.0 (Phase IV)
working
on there too and it works fine.
VAX KA655X simulation is... sluggish. I'm used to running it on
1.xGHz
x86_64
CPUs (Atom or AMD) with fast hard drives or SATA SSD. The CPU speed
makes it slow but imagine it's as fast or faster than a real late

VAX. It's
by no means perishingly annoying, it just takes a little thinking
between
operations. I think I may be spoilt as I've never used a real VAX.
Overall so far I'm very impressed with the RasPi and it will fulfil
the
roles I
need for it. When I get hold of a few more I am going to try and
build a
VMS
cluster that uses less than 6W :) I will also have one permanently
running
a
PDP-11 (something that I've not managed since I had my Cobalt Qube2
running) RSX-11MP system.
Oh and CPU Idle works just fine in PDP-11 and VMS-VAX simulations.
To be
honest even when I compiled all the simulator binaries for SimH (as
a
stress
test) and when I was running the SYSGEN in RSX-11M it barely got
much
worse temperature-wise than hot to touch a the CPU. On a board that
only
uses 300mA with no USB and Ethernet active it hardly has a lot of
energy
to
dissipate as heat in the first place!
I'm gonna have a LOT of fun with these :D
