This wishlist bug has been open a year without any activity. I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on.
In case you want to work on that, consider writing a blueprints [1] and spec [2]. I'll recommend to read [3] if not yet done. The effort to implement the requested feature is then driven only by the blueprint (and spec).

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1355921 Title: [libvirt] When guest configured for threads, poor VCPU accounting Status in OpenStack Compute (nova): Opinion Bug description: Noticed while testing: https://blueprints.launchpad.net/nova/+spec /virt-driver-vcpu-topology I have a host advertising 16 VCPUs (2 sockets, each 8 cores). Each core happens to have 8 threads. (This is on a beefy POWER8 system). With the above blueprint, I can now create a 1 socket, 2 core, 8 thread guest. All works fine, except that I noticed "Free VCPUS: 0' even though I'm really only using two cores. I'd think I would see 14 free VCPUs in this scenario.
