Description

Presently, bhyve detects certain the availability of certain CPU capabilities such as APICv during loading. If it fines any of these capabilities, it enables them globally for all VMs. It does so in a way that makes it challenging to create a VM which does not use those capabilities. Being able to test various combinations, or the total absence of those capabilities when running on a CPU that features them all would be useful. We should start splitting up how the capabilities are detected and then later activated.
