Blueprints hide-hypervisor-id-flavor-extra-spec [1] and add-kvm-hidden-feature [2] allow hiding KVM's signature for guests, which is necessary for Nvidia drivers to work in VMs with passthrough GPUs. While this works well for linux guests on KVM, it doesn't work for Windows guests. For them, KVM emulates some HyperV features. With the current implementation, KVM's signature is hidden, but HyperV's is not, and Nvidia drivers don't work in Windows VMs. This change generates an extra element in the libvirt xml for Windows guests on KVM which obfuscates HyperV's signature too, controlled by the existing image and flavor parameters (img_hide_hypervisor_id and hide_hypervisor_id correspondingly). The extra xml element is <vendor_id state='on' value='1234567890ab'/> in features/hyperv.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
