I have a new Openstack Mitaka install with Foreman/Puppet provisioning front end to Openstack with the latest Win2012 image downloaded from Cloudbase and I followed the instructions to add this image to Openstack.
The defaul Openstack setup was: virttype=qemu, which works for the Linux Openstack VMs, but when I change it to : virttype=kvm, the Windows2012 image still gives the same bsod error. And also the Linux VMs don't fully complete their builds with the KVM virt_type set.
This is all running on Centos 7.
