Yes Dan, you are right.
I am using the stackOps distro, and the network 1 was created before
quantum instalation, i don't know how neather why.
Now I have these two networks
root at nova-controller:~/quantum-2011.3# nova-manage network list
id IPv4 IPv6 start address
DNS1 DNS2 VlanID project
uuid
3 192.168.1.160/27 None 192.168.1.162
8.8.4.4 None None None
85b629fc-7fec-4fdd-b842-76a3711e83d9
4 192.168.1.128/27 None 192.168.1.130
8.8.4.4 None None None
a52b0d7b-791a-4e81-8772-8df04b9ccd70
Anyone knows how can i instantiate a vm and associate it to one of these
networks?
