There are times when I want to re-use an existing guest setup, but re-install or boot a Live image or something. For this reason I would like to be able to select what the boot device should be.
This has been added upstream: http://hg.et.redhat.com/virt/applications/virt-manager--devel?cs=4770f435ab01 You should now be able to go to Details->Boot Device to choose the boot method for a guest. There are a couple screen shots here: https://www.redhat.com/archives/et-mgmt-tools/2008-March/msg00017.html
