Answering my own question: I forgot to install the virtio serial driver... Now the qemu-ga starts... ________________________________ Van: Dominique Ramaekers Verzonden: donderdag 12 november 2015 23:50 Aan: libvirt-users(a)redhat.com Onderwerp: Qemu-ga on Windows 10 Hi, I have a windows 10 guest with qemu-ga-x64.msi installed from the fedora virtio iso. qemu-ga version is 0.12.1 host qemu version is 2.1.0 (I know its older but in this version the active block commit works perfectly...) libvirt version 1.2.12 I have these lines in my xml: <channel type='unix'> <source mode='bind' path='/var/lib/libvirt/qemu/channel/target/PCVIRTmbe.org.qemu.guest_agent.0'/> <target type='virtio' name='org.qemu.guest_agent.0' state='disconnected'/> <alias name='channel0'/> <address type='virtio-serial' controller='0' bus='0' port='1'/> </channel> /var/lib/libvirt/qemu/channel/target/PCVIRTmbe.org.qemu.guest_agent.0 exists on the host and the rights seems to be all right. On the guest, the folder C:\ProgramData\qemu-ga exists Still, I can't start the qemu-ga service. I get this error: Can't start QEMU GuestAgent-service on the local computer Error 1053: The service didn't answer correctly on the start command (or something like this, the error message in in Dutch) If I start the qemu-ga from the cmd I get this error: error opening path error opening channel failed to create guest agent channel failed to initialize guest agent channel Does anybody got an idea how to resolve this problem? Thanks in advance. Dominique.
