Strange, I can't seem to get the virtio-win-0.1-15.iso vioser drivers working with either qemu.git or qemu-kvm.git. I thought I was using them for XP SP3, but apparently I had switched over to using RHEL6ga drivers at some point (virtio-win-1.1.16.iso), which I believe are older than the Fedora ones you're using. However, there was an issue with the RHEL6ga drivers where an ERROR_SYSTEM_NO_RESOURCES was sometimes being reported in place of what where I'd normally expect an EOF with the linux drivers. So my guess is that has since been changed to report ERROR_OPERATION_ABORTED instead, so please also apply the following patches and see if these fix the issues you're having: 1) qemu-ga: fix incorrect getopt_long() usage https://github.com/mdroth/qemu/commit/b5f4349763936007e1a33ba99d9ffb6b75a49b36 2) qemu-ga: win32, treat ERROR_OPERATION_ABORTED as EOF https://github.com/mdroth/qemu/commit/7418bbf903e639ec22c394771f5ff03f18bd1275 Thanks
