Adding storage to a guest

Hi,

I have a Ubuntu-server as guest on Byhve/FreeBDS 13

I tried to add some extra storage, so added

disk2_dev="custom"
disk2_opts="sectorsize=512"
disk2_type="virtio-blk"
disk2_name="disk2.img"

to the config file. Unfortunately, it doesn't show under /dev/vda* in 
the guest.

Where is my mistake ?

TIA,

Cheers,

Xavier
