Hi All !
I found a new bug in Floppy controller -- usually I report bugs to Avi,
but since he is not here, I decided to report to mailing list.
This bugs prevents Windows booting with Floppy inserted.
Qemu command to reproduce:
./qemu-kvm -fda myfloppy.vfd -cdrom /isos/windows/Windows2003_r2_VLK.iso -boot d
It won't boot from CD-ROM (black screen), and will stuck during booting from hard disk.
It affects both Intel & AMD systems, but not Qemu emulator. (-no-kvm works)
I did bisect and found bug in KVM userspace git:
kvm-87-239-gbb598da ( commit bb598da496c040d42dde564bd8ace181be52293e by Glauber Costa)
on 6.7.2009.
Can you look at it please ?
