Hello. I believe I've found a bug in libvirtd but not sure.
Using libvirt-0.8.1 and virtinst-0.500.3 (and virt-manager-0.8.4 and Python 2.6.5 if
relevant) on a linux system (kernel 2.6.35-rc4 if relevant)
I ran this virt-install command , which is trying to create a windows2k virt mc by
importing an existing system consisting of a boot-floppy image on a file (the boot device)
and one real disk device on /dev/sdc
virt-install --connect qemu:///system --name=RH7win2k --ram=392 --cpuset=0
--description="win2k on RH7 disk on usb, nat network" --import
--network=network=default --virt-type=kqemu --accelerate --vnc --vncport=5905
--video=cirrus --disk=/mnt/soltbakp/commonfiles/win2k_boot.floppage,device=floppy
--disk=/dev/sdc,device=disk --os-type=windows --os-variant=win2k
and it fails like so
ERROR internal error unknown boot device 'floppy'
ERROR internal error unknown boot device 'floppy'
Traceback (most recent call last):

if ret is None:raise libvirtError('virDomainDefineXML() failed', conn=self)
libvirtError: internal error unknown boot device 'floppy'
but if I repeat the command with just interchanging the order of the floppy and disk
definitions, (so that I am telling it to use the disk as boot device), then the
virt-install works ok as far as setup goes, but of course fails during boot (and I can
then alter the boot order back to what I should be in virt-manager and it then boots)
Is this a bug? and if so is it already known? (I couldn't find how to search the
archives for this list and don't see it in google)

Can you provide the full output of the virt-install command with the --debug flag?

Below is what it wrote to my ~/.virtinst/virt-install.log(without the --debug flag but
according to the man page it's the same debug output)
Interesting to see that it generated what looks to be a good .xml but it did not put that
into my libvirt/qemu directory.
Seems it just does not know about booting from a floppy?
If you need something else let me know.

Whoops, this is a virtinst bug. The boot device is actually supposed to
be 'fd', not 'floppy'. Fixed upstream now:
http://hg.fedorahosted.org/hg/python-virtinst/rev/4d0ea2274ffd
As a work around, you should be able to copy the XML that virtinst was
generating, change 'floppy' to 'fd', virsh define it and proceed from
there. Thanks for the report.
