[Qemu-devel] [Bug 1593756] [NEW] qemu-ga won't start on Windows 8.1 guest

[Halogene]

Public bug reported:

System: Arch Linux, kernel 4.6.2
VM created with virt-manager 1.3.2
qemu version 2.6.0
Windows guest: 8.1, with latest updates (as of now)
Drivers installed from virtio-win iso image (arch package version 0.1.118.2-1)
  in particular: vioserial driver version 62.73.104.11800

I can start the Guest Agent VSS Provider manually, but the Guest Agent
itself doesn't come up. When launched from Console, I get the following:

<timestamp>: critical: error opening path
<timestamp>: critical: error opening channel
<timestamp>: critical: failed to create guest agent channel
<timestamp>: critical: failed to initialize guest agent channel

(As possible side effects I have experienced that suspend / resume of
the VM only works when I resume, suspend again and resume again. After
first resume the VM's screen is frozen and doesn't accept any input.
After second resume, all seems to be well.)

** Affects: qemu
     Importance: Undecided

Oh, qemu-ga worked before (not sure whether before upgrade to kernel
4.6.x or before upgrade to qemu 2.6.0 though). Re-installed a clean
windows into a new VM to verify issue.

It turned out that this is not a bug but instead I overlooked to add a
channel for qemu-ga via virt-manager. Don't know how it got lost on the
working machine, but nvm, it works now.

Anyone feel free to close this (didn't find an option to do so).
