Comments on Virtualization With KVM On Ubuntu 9.10
Virtualization With KVM On Ubuntu 9.10 This guide explans how you can install and use KVM for creating and running virtual machines on an Ubuntu 9.10 server. I will show how to create image-based virtual machines and also virtual machines that use a logical volume (LVM). KVM is short for Kernel-based Virtual Machine and makes use of hardware virtualization, i.e., you need a CPU that supports hardware virtualization, e.g. Intel VT or AMD-V.

The dual-use of acronyms is widespread, especially considering the different disciplines that make use of them. But, to have the same acronym found within the same discipline shouldn't be too surprising, either, considering that technology continues to advance, hence the potential application for new acronyms continues to increase.
In this case, both acronyms (one hardware one software) both simply make sense. So we understand by the context! Languages are even worse, by the way!
KVM is short for Keyboard, Video and Mouse and is hardware device.
Yes, regrettably, the selection of "KVM" to mean "Kernel Virtual Machine" was done without regard to the prevalence of KVM's use as an acronym of "Keyboard, Video, Mouse".
Under Ubuntu Lucid Lynx the vmbuilder command became a little bit more finicky with its command line arguments. It no longer supports the --tmpfs option and the --firstboot option only works without the = sign.
The command line must now look like this to work:
vmbuilder kvm ubuntu --suite=karmic --flavour=virtual --arch=amd64 --mirror=http://192.168.0.100:9999/ubuntu -o --libvirt=qemu:///system --ip=192.168.0.101 --part=vmbuilder.partition --templates=mytemplates --user=administrator --name=Administrator --pass=howtoforge --addpkg=vim-nox --addpkg=unattended-upgrades --addpkg=acpid --firstboot boot.sh --mem=256 --hostname=vm1 --bridge=br0
Note the absent = sign between --firstboot and boot.sh and the absent option --tmpfs
