Setting up interfaces on ubuntu under bhyve

[hiren panchasara]

(keep me cc'd please; I am not subscribed)

I usually create a freebsd vm with:
sh /usr/share/examples/bhyve/vmrun.sh -c 2 -m 2048M -t tap2 -t tap3 -t
tap4 -d freebsd.img -i -I freebsd.iso vm1 

and run it with:
sh /usr/share/examples/bhyve/vmrun.sh -c 2 -m 2048M -t tap2 -t tap3 -t
tap4 -d freebsd.img vm1

I am trying to bring up an ubuntu vm and following
https://www.monkeybrains.net/support/bhyve (file based and not zfs vol
based)

If I want to create a similar-ish vm:
# bhyve -c 2 -m 2048M -H -P -A -s 0:0,hostbridge -s 1:0,lpc -s
 2:0,virtio-net,tap2,tap3,tap4 -s
 3,ahci-cd,./ubuntu-13.10-server-amd64.iso -l com1,stdio -s
 4,virtio-blk,./linux.img linux

VM comes up but I don't see vtnetN interfaces there as I would on
the freebsd vm. On the freebsd vm, I see vtnet0, vtnet1 and vtnet2.

the tap interfaces are not even created on the host. 

What am I missing? 

Cheers,
Hiren
