Yes, you read the subject right; add floppy support to xm internal. Let's just say I didn't do this by choice. In any case, there was a cryptic comment in xenXMParseXMLDisks() that said: /* Xend (all versions) put the floppy device config * under the hvm (image (os)) block */ What this actually means is that we shouldn't parse the floppy stuff to put it in the "disks =" section of the /etc/xen configuration file, since it doesn't have meaning there. Instead, floppy disks go at the top-level of a Xen config file, like: fda = '/var/lib/xen/images/floppy.img' fdb = '/var/lib/xen/images/floppy2.img' That's exactly what this patch does. In combination with a couple of other small patches to virt-install (which I will post to the appropriate list), I was able to use a floppy disk to hold the kickstart for a fully virtualized Xen guest install.
