Subject: Re: How is this overallocation possible?
 
If I recall correctly, default CPU allocation ratio is 16. Which means you can multiply CPU cores by 16 and it will be fine.
Please check https://docs.openstack.org/nova/yoga/admin/scheduling.html#allocation-ratios for more details on that.

Horizon just don't know what ratio is set so shows just CPU cores of compute.

See image below. How can I be using 38 vcpus on a compute with 24 total? Is this an error in horizon?
