Hi, Anyone else using vmbuilder with Ubuntu's 10.x Lucid Lynx (Alpha3, I know) and cursing the change in options that just happened recently? I've been playing around building VMs (based on Karmic) and tossing them away since it was so quick. Now that I've upgrade to a newer version of Lucid, it's all busted. Sigh... This would be a good talk too, about building and using VMs. Here's the script I whipped up to help automate things, which is now busted. Sigh... I realize I need to just look in the docs, but they a) suck and b) aren't easily found. Nor is any list of changes in the options listed nicely either. Grrr!!!! THanks, John #!/bin/sh # My own script for building and starting VMs more easily, based on # the instructions given at: # # http://www.howtoforge.com/virtualization-with-kvm-on-ubuntu-9.10 # # Version 0.1 - 12/29/2009 # if [ $# -ne 3 ]; then echo "Usage: $0 hostname ip username" echo " IP is last octet of the 192.168.1/24 subnet" echo exit fi euid=`id -u` if [ $euid -ne 0 ]; then echo "Error!
