I'm unaware of vmstated.  Checking its manpage it does not yet seem to have
feature parity with vm-bhyve.  Many of the things I think you want a VM
manager to do are also perhaps a bit harder to do in C (e.g. forking and
execing tmux to access the serial console) compared to a scripting language.

Note that jail management today via jails.conf doesn't require a running
daemon, so that seems a bit curious, though perhaps the goal is to handle
auto-restarting if a VM exits unexpectedly?
