This is known issue of virtio-serial, unfortunately I cannot find publicly available binary, but should be fixed by: https://github.com/YanVugenfirer/kvm-guest-drivers-windows/commit/4f979020d9d532afa3970203127f67bc6a5749bf > > Christophe > > ___ > Spice-devel mailing list > spice-de...@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/spice-devel >

The virtio-win-0.1-30 drivers are the newest ones I know of.

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?

What version of virtio-serial were you using? The old virtio-serial driver from spice-guest-tools-0.1 had similar issues. Christophe pgpsuydkg0cDM.pgp Description: PGP signature
