Previously bhyve obtained a "read lock" on the memory map for ioctls needing to read the map by locking the last vCPU. This is now replaced by a new per-VM sx lock. Modifying the map requires exclusively locking the sx lock as well as locking all existing vCPUs. Reading the map requires either locking one vCPU or the sx lock. This permits safely modifying or querying the memory map while some vCPUs do not exist which will be true in a future commit.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
