You need to unref @cfg.

This include is because of bhyveConnPtr type I assume. Well, that one is defined in bhyve_utils.h which is the file you should be including.
After you've done that you'll find that bhyve_capabilities needs to include bhyve_conf.h" because of virBhyveDriverGetConfig call. But that's okay - you can replace include of bhyve_utils.h there with bhyve_conf.h:

With that squashed in, and unrefing @cfg you have my ACK.
