[Qemu-devel] Virtio drivers for WindowsServer 2012R2 network problems no outgoing traffic in Openstack

[Daniel Seybold]

Hi qemu developers,

currently I'm facing a tricky issue when I'm using the Virtio drivers 
(Fedora [1]) for a WindowsServer2012R2 virtual machine on Openstack

I've created a WindowsServer Image following this tutorial [2]. I've 
installed the virtio drivers  but without the Cloud-Init step.

I've created the Image in Openstack and started a VM.
I'm able to connect to the VM via powershell or remote desktop but I'm 
not able to download any source from the internet.
I always receive a timeout.

Openstack Version: Kilo
QEMU emulator version 1.5.3 (qemu-kvm-1.5.3-86.el7_1.5), Copyright (c) 
2003-2008 Fabrice Bellard
virtio drivers: virtio-win-0.1.102

I've done the same steps on an older Openstack setup with
virtio drivers: virtio-win-0.1.96
and everything works without a problem.

Openstack Version: Icehouse
QEMU PC emulator version 0.12.1 (qemu-kvm-0.12.1.2-2.448.el6_6), 
Copyright (c) 2003-2008 Fabrice Bellard
virtio drivers: virtio-win-0.1.96

It is definately not related to Openstack Security groups or netowork 
issus on the host.
There is also a unix VM on the host without any network issues.

Does anyone have a clue how to solve this issue?

Thanks in advance for your help!

Cheers,
Daniel
