FYI, I just tried this and it appears to work. That is, with the
following:
==> /boot/loader.conf <==
if_tap_load="YES"
vboxdrv_load="YES"
==> /etc/sysctl.conf <==
net.link.tap.user_open=1
net.link.tap.up_on_open=1
net.link.ether.inet.proxyall=1
==> /etc/rc.conf <==
cloned_interfaces="bridge0 tap0 tap1"
ifconfig_bridge0="addm tap0 addm tap1 192.168.1.121/29"
gateway_enable="YES"
and with the VM network adapters configured as bridged to the tapX
devices, the guest em0 interfaces configured with IP addresses in the
bridge0's subnet and with default routes to the bridge0 ip, networking
seems to come up fine in the guests. (I'm still starting the VMs
manually so it hasn't been verified in fully autonomous startup.)
