“Unlike virt-manager, virt-install is a command line tool that
allows you to create KVM guests on a headless server. You may ask
yourself: “But I can use vmbuilder to do this, why do I need
virt-install?” The difference between virt-install and vmbuilder is
that vmbuilder is for creating Ubuntu-based guests, whereas
virt-install lets you install all kinds of operating systems (e.g.
Linux, Windows, Solaris, FreeBSD, OpenBSD) and distributions in a
guest, just like virt-manager. This article shows how you can use
it on an Ubuntu 11.04 KVM server.”
