I tried to boot a new instance with two NICs, but seems I can't setup
network_id to a single one, that means I have to create at least two VLANs
for NICs. Is there any way that I can boot my instance with two NICs and
assign the ip in a single VLAN? And why this is not allowed currently?
Thanks.

Here's the error message I saw from output:
nova --debug boot --flavor 11033 --image
