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? -- John Baldwin
