This will do basically the same thing and also pull in your preferences for RAM size and disk file size from the profiles -- so you still get fully automatic and repeatable network installs. Koan is paravirt only at the moment though more virt types are next up on my list. http://cobbler.et.redhat.com --Michael

This means you do get the new ''boot=n'' option for PXE fullyvirt guests. We''ve not had time to get PXE support into virt-install or virt-manager for F7 GA release, but we''ll be releasing an update with it shortly after GA.

(wink wink, nudge nudge) I know quite a few large install bases have environments where PXE is not an option either due to not having control over DHCP :)
