Hello David,

Could you please provide more information about your setup,
including qemu, and seabios versions, as well as qemu command line.
In any case build 65 was not a release build, This problem should be fixed in build 73.

Comment 2 Mike Cao 2013-11-19 22:06:58 EST
I do not think it is a virtio-win bug .
Could you show the qemu version to make sure whether it is dup of https://bugzilla.redhat.com/show_bug.cgi?id=1031552 

Comment 4 Ronen Hod 2013-11-20 04:43:16 EST
In any case, we will update the Fedora drivers soon.

(In reply to Mike Cao from comment #6)
> BTW ,there is no signed drivers for windows 2012 R2

I believe that the 2012 drivers will work for them. Will they?
2012R2 is too new. Sometime soon.
Comment 12 David Hill 2013-11-20 09:31:18 EST
Well, I found a workaround this issue...

1) install Windows 2012R2 with the IDE disk driver
2) Install cloud-init and sysprep the VM
3) copy the image in glance
4) deploy the VM

et voila!  It works.

Seems like the only part that's not working with the "latest" virtio windows drivers is the installation part.

The version qemu/kvm/etc versions we're using are the latest from RHEL 6.4 / rdo havana.

Also, the windows drivers I'm using are the ones in the ISO on http://alt.fedoraproject.org/pub/alt/virtio-win/latest/images/
Comment 14 David Hill 2013-11-20 09:37:06 EST
I'm using virt-install with pretty much no command line (or almost none).  It breaks if I add --disk path=/my_image,bus=virtio,cache=none ...
Comment 16 Cole Robinson 2013-11-20 15:25:53 EST
Updated drivers are pushed now:

Comment 17 David Hill 2013-11-20 15:47:06 EST
Thank you!  Those drivers fixed my disk drivers issue ...

We generated the official Microsoft Windows Server 2012 R2 Eval OpenStack images using VirtIO 0.1-52 without issues:


The fully automated procedure to generate them is available here: 


Note VirtIO 0.1-65 causes a blue screen when attaching a volume so we had to stick with 0.1-52. 

We're going to test 0.1.74 today and update the images if everything is ok.
