host info:
# uname -r&& rpm -q qemu-kvm-rhev
guest info:
# rpm -q virtio-win

Comment 4 John Snow 2015-06-30 20:01:43 UTC
The problem is caused by QEMU's usage of the 1.44MB FDrive type as a default when no floppy is inserted. Our virtio-win drivers ship on a 2.88MB floppy drive image. There is currently no CLI interface to specify that a 2.88MB drive is desired, except by having an image present at boot.

I am delaying this BZ because it needs to be worked on upstream and will likely involve more research before a proper fix is identified.

I recommend releasing documentation informing users that it would be best to boot their machine with a 2.88MB FD image if they desire that functionality. In this particular case, this image is generally only useful at boot during a new VM installation, so impact is expected to be minimal.

Comment 6 John Snow 2016-05-16 18:14:56 UTC
Should be fixed by rebase to 2.6.0.
