The old virtio-serial driver > from spice-guest-tools-0.1 had similar issues. 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? > > Christophe -- Best Regards, Dunrong Huang _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/spice-devel
