The driver I downloaded is from
http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/bin/virtio-win-0.1-30.iso.

After mounting ISO, I found following content:
$ cat win7/x86/vioser.inf
[Version]
Signature="$WINDOWS NT$"
Class=System
ClassGuid={4d36e97d-e325-11ce-bfc1-08002be10318}
Provider=%REDHAT%
DriverVer=07/03/2012,61.63.103.3000
CatalogFile=vioser.cat
DriverPackageType = PlugAndPlay
DriverPackageDisplayName = %VirtioSerial.DeviceDesc%

Is there a newer driver that has fixed the issue?
