That's how it is on physical machines (I image lab computers and have to clean up the udev rules file among other things) and would expect the same behavior from virtual machines. The limitations of virt-clone are known and are being addressed in virt-sysprep... which hasn't made it to RHEL yet I don't think... but you can find out about it here: http://rwmj.wordpress.com/2011/10/08/new-tool-virt-sysprep/ TYL, -- Scott Dowdle 704 Church Street Belgrade, MT 59714 (406)388-0827 [home] (406)994-3931 [work]
