In version python-virtinst-0.400.3-1.el5 Example: virt-install --connect test:///default --name foo --ram 64 --pxe --nographics --noautoconsole --disk pool=default,size=.001 ERROR A disk path must be specified. (use --prompt to run interactively) The above command should succeed, creating a new storage volume. This was fixed upstream several weeks ago: http://hg.et.redhat.com/cgi-bin/hg-virt.cgi/applications/virtinst--devel/rev/676312613510 Specifying floppy devices is new functionality introduced by the rebase, so this technically isn't a regression (and by extension the bug hasn't existed in any released version). However, the patch is simple, low risk, and was caught using a command line test suite upstream (so I have high confidence that the change doesn't cause unintended breakage).
Fixed in python-virtinst-0.400.3-2.el5. Closing as NEXTRELEASE, since this bug has not existed in any released package as it was brought in by the rebase.
