[libvirt] qemu can't parse floppy cmdline



Hi Dan,

With qemu-0.12.2-5.fc13.x86_64 in fedora, libvirt is generating a cmdline
which qemu-kvm can't parse. XML is:

<domain type='kvm'>
  <name>winxp_32</name>
  <uuid>3485e26d-c370-c0b0-32e2-a041a12f5cfc</uuid>
  <memory>1048576</memory>
  <currentMemory>1048576</currentMemory>
  <vcpu>1</vcpu>
  <os>
    <type arch='x86_64' machine='pc-0.11'>hvm</type>
    <boot dev='hd'/>
  </os>

  <clock offset='localtime'/>

  <on_crash>restart</on_crash>
  <devices>
    <emulator>/usr/bin/qemu-kvm</emulator>
    <disk type='file' device='disk'>
      <driver name='qemu'/>
      <source file='/mnt/devel/vms/disks/winxp_32.qcow2.img'/>
      <target dev='hda' bus='ide'/>
      <address type='drive' controller='0' bus='0' unit='0'/>
    </disk>
    <disk type='file' device='cdrom'>

      <source network='default'/>
      <target dev='vnet0'/>
    </interface>
    <serial type='pty'>
      <target port='0'/>
    </serial>
    <console type='pty'>
      <target port='0'/>
    </console>
    <input type='tablet' bus='usb'/>
    <input type='mouse' bus='ps2'/>
    <graphics type='vnc' port='-1' autoport='yes'/>
    <sound model='es1370'/>
    <video>
      <model type='vga' vram='9216' heads='1'/>
    </video>
  </devices>
</domain>

The generated cmdline is:

LC_ALL=C PATH=/sbin:/usr/sbin:/bin:/usr/bin QEMU_AUDIO_DRV=none

-vga std -device ES1370,id=sound0,bus=pci.0,addr=0x5 -device
virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x3

can't parse: "isa-fdc,driveA=drive-fdc0-0-0"


If I drop the floppy dev and controller, the guest boots, but a few warnings
are printed. Not sure if any of this reflects qemu bugs or libvirt bugs:
