bhyve(load) does not start in jail on -CURRENT

Hi,

I'm using jails to run some tests with bhyve and this setup works for me
with 15.0-RELEASE, but does not with 16.0-CURRENT.

The setup is as follows:

jail.conf:

testrunnergit {
  enforce_statfs = 2;
  devfs_ruleset = 44;
  exec.clean;
  exec.consolelog = /var/log/bastille/testrunnergit_console.log;
  exec.start = '/bin/sh /etc/rc';
  exec.stop = '/bin/sh /etc/rc.shutdown';
  host.hostname = testrunnergit;
  mount.devfs;
  mount.fstab = /usr/local/bastille/jails/testrunnergit/fstab;
  path = /usr/local/bastille/jails/testrunnergit/root;
  osrelease = 16.0-CURRENT;

  vnet;
  vnet.interface = e0b_bastille1;
  exec.prestart += "jib addm bastille1 vtnet0";
  exec.prestart += "ifconfig e0a_bastille1 description \"vnet0 host interface for Bastille jail testrunnergit\"";
  exec.poststop += "ifconfig e0a_bastille1 destroy";
  allow.chflags = 1;
  allow.raw_sockets = 1;
  allow.vmm = 1;
  allow.mount;
  allow.mount.devfs;
  allow.mount.fdescfs;
  allow.mount.procfs;
  mount.fdescfs;
  mount.procfs;
}

When I try to run bhyveload:

root@testrunnergit:~ # bhyveload -m 1024 -d /var/cache/libvirt-tck/os-x86_64-hvm/disk-freebsd-11.1.img tck32424
bhyveload: vm_create: Operation not permitted (An unprivileged user must run VMs in monitor mode)
root@testrunnergit:~ #

root@freebsd16-current:~ # jls -j testrunnergit allow.vmm
true
root@freebsd16-current:~ # devfs -m /usr/local/bastille/jails/testrunnergit/root/dev rule show
100 include 4
200 path vmmctl unhide
300 path vmm unhide
400 path vmm/* unhide
500 path tap* unhide
600 path mem unhide
700 path kmem unhide
800 path nmdm* unhide
900 path pci unhide
1000 path io unhide
1100 path pf unhide
root@freebsd16-current:~ #

Am I missing anything?

Thanks,
Roman
