Description of problem:
Define a guest with floppy disk then start the guest,the floppy disk can't be discoverd by the guest.

Version-Release number of selected component (if applicable):
kvm-83-229.el5
libvirt-0.8.2-18.el5
kernel-2.6.18-252.el5


How reproducible:

2.Virsh start the guest
3.In the guest run fdisk -l and cat /proc/partitions

Actual results:
The floppy disk can't be discoverd.

Expected results:


Additional info:
Look at the log /var/log/libvirt/qemu/nfs_test.log
