kvm-83-207.el5

How reproducible:
100%

Steps to Reproduce:
1.run windows xp guest without floppy option
/usr/libexec/qemu-kvm  -M rhel5.6.0 -m 2G -smp 2 -name winxp -uuid 123465d2-2032-848d-bda0-de7adb149048 -boot cdn -drive file=/mnt/winxp.img,if=virtio,boot=on,bus=0,unit=0,format=qcow2,cache=off -net nic,macaddr=54:52:00:27:12:23,vlan=0,model=virtio -net tap,vlan=0,script=/etc/qemu-ifup -serial pty -parallel none -usb -usbdevice tablet   -monitor stdio   -spice host=0,ic=on,port=5937,disable-ticketing -qxl 1 -drive file=/mnt/data.img,if=virtio,format=qcow2,cache=off

2.check block info
(qemu) info block
virtio0: type=hd removable=0 file=/mnt/winxp.img ro=0 drv=qcow2
virtio1: type=hd removable=0 file=/mnt/data.img ro=0 drv=qcow2
ide1-cd0: type=cdrom removable=1 locked=0 [not inserted]
floppy0: type=floppy removable=1 locked=0 [not inserted]
sd0: type=floppy removable=1 locked=0 [not inserted]

No floppy inserted.

3.change floppy to new file
(qemu) change floppy0 /mnt/virtio-win-1.1.10-0.vfd

4. check block info again
(qemu) info block
virtio0: type=hd removable=0 file=/mnt/winxp.img ro=0 drv=qcow2
virtio1: type=hd removable=0 file=/mnt/data.img ro=0 drv=qcow2
ide1-cd0: type=cdrom removable=1 locked=0 [not inserted]
floppy0: type=floppy removable=1 locked=0 file=/mnt/virtio-win-1.1.10-0.vfd ro=0 drv=raw
sd0: type=floppy removable=1 locked=0 [not inserted]

There is no screenshot attached.

What happens when you try to access the floppy, say "dir a:" in cmd?

If you try the same recipe with a CD-ROM, does it work?

Sorry, forget to attach screen shot. Now reproduce this bug as following:

1. start guest without floppy and cdrom
(qemu) info block
ide0-hd0: type=hd removable=0 file=/root/test/winxp.qcow2 ro=0 drv=qcow2
ide1-cd0: type=cdrom removable=1 locked=0 [not inserted]
floppy0: type=floppy removable=1 locked=0 [not inserted]
sd0: type=floppy removable=1 locked=0 [not inserted]

2. insert cdrom and floppy
(qemu) change floppy0 /usr/share/virtio-win/virtio-drivers.vfd
(qemu) change ide1-cd0 /root/WindowsXP-32.iso 
3. check block status
(qemu) info block
ide0-hd0: type=hd removable=0 file=/root/test/winxp.qcow2 ro=0 drv=qcow2
ide1-cd0: type=cdrom removable=1 locked=0 file=/root/WindowsXP-32.iso ro=0 drv=raw
floppy0: type=floppy removable=1 locked=0 file=/usr/share/virtio-win/virtio-drivers.vfd ro=0 drv=raw
sd0: type=floppy removable=1 locked=0 [not inserted]
4. check cdrom and floppy in windows guest

After step 4, we can only see cdrom but no floppy in My computer of windows guest as attached screen shot.

Comment 5 Markus Armbruster 2011-08-08 15:56:45 UTC 
Not a customer bug, no progress for 9 months, and not serious enough to justify further investigation at this stage of the RHEL cycle.  Closing WONTFIX.  If you disagree, please reopen.
