This problem disappeared in newer version http://download.devel.redhat.com/brewroot/packages/virtio-win-prewhql/0.1/37/win/virtio-win-prewhql-0.1.zip |
Description of problem: Sometimes when I boot the Windows XP guest some or all of virtio_serialports are missing in \\.\ and \\Device\. Guest reboot usually helps or leads to different missing ports. Version-Release number of selected component (if applicable): Guest: Windows XP SP3 virtio-win-0.1-30 Host: Fedora 17, kernel 3.5.3-1.fc17.x86_64 qemu-kvm-1.0.1-1.fc17.x86_64 How reproducible: Very often. In over 60% cases some of the ports are missing and over 30% none of the ports is initialized. Some of the ports also disappear after the reboot. Steps to Reproduce: 1. boot Windows XP guest with virtio_serialport 2. look for \\.\$symbolic_link or \\.\\{6FDE7547-1B65-48ae-B628-80BE62016026}#VIOSerialPort#.. or \\Device\vport* device ex. using WinObj. Actual results: Some or none of virtio_ports is present. CreateFile() with expected name fails. Expected results: All of virtio_ports should have GUID, vport and symbolic names and should be prepared for use.
