After installing Centos6 and starting the guest there is no network

I am using the following commands to load the kernel:
grub-bhyve -m device.map -r hd0,msdos1 -M 2048 centos
ls (hd0,msdos1)/
linux (hd0,msdos1)/vmlinuz-2.6.32-642.el6.x86_64
root=/dev/mapper/VolGroup-lv_root
initrd (hd0,msdos1)/initramfs-2.6.32-642.el6.x86_64.img
boot
and start the guest:
bhyve -c 4 -m 2048M -A -H -P \
-s 0:0,hostbridge \
-s 1:0,lpc \
-s 2:0,virtio-net,tap0 \
-s 3:0,virtio-blk,/dev/zvol/tank4/centos6v \
-l com1,stdio \
centos
The following has been added to /etc/rc.conf:
cloned_interfaces="bridge0 tap0"
ifconfig_bridge0="addm wlan0 addm tap0"
/boot/loader.conf
vmm_load="YES"
nmdm_load="YES"
if_bridge_load="YES"
if_tap_load="YES"
What I am missing?

I tried to set up the network following this guide:
http://www.krizna.com/centos/how-to-setup-network-in-centos-6/
The dhcp option didn't work (can't obtain the IP). When assigning the IP
statically the network can be started but then only the host is visible.
Neither the DNS nor the gateway are visible:
[root@localhost network-scripts]# pwd

Am I missing some additional setting on the host?
