Whiteboard

A multi-head feature is already implemented for the Libvirt hypervisor but was not approved due to a missing feature spec/blueprint: https://review.opendev.org/c/openstack/nova/+/828676

Note that this implementation only addresses a multi-head operation for Linux-based guests. For Windows guests one have to add multiple video devices instead of setting Libvirt's "head" XML attribute.
