And before anyone asks, yes I do have the device nodes in /dev (created
for each vndX with "sh MAKEDEV vndX" ) and the XEN0 config has been
modified to support 50 vnd devices).

This is the script I'm using to lauch all VMs:


#!/bin/sh

if [ $# -eq 0 ]; then
    echo "Usage: `basename $0` vmid [-c]"
    exit 1
fi

ID=${1}
shift
DEV=`vnconfig -l | grep vnd${ID}: | grep -v "not in use"`
if [ ! -z ${DEV} ]; then
    echo "vnd${ID} already in use"
    exit 1
fi

(cd /dev && sh MAKEDEV vnd${ID})

vnconfig vnd${ID} /xen/vm/netbsd.${ID}
xm create /xen/conf/netbsd.${ID} $*
