Title:
In Vlan mode can't create a network when --vlan option is not set
Status in OpenStack Compute (Nova):
Fix Released
Bug description:
In Vlan mode when I tried to create a network without setting the
--vlan mode, I got the DuplicateVlan exception.
$ nova network-create --fixed-range-v4 192.168.3.1/24 net

This is because "vlan" is set to the default value 100, if the --vlan option
isn't set.
So I think we should make "vlan" an essential option to fix to bug.
