[libvirt] [PATCH]: Add floppy support to xm_internal

[Chris Lalancette]

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.
