Subject RE: VLANS in Advance Networking NOT NEEDED.
Date Wed, 08 Aug 2012 01:01:00 GMT
The ability to deploy SG in advance zone is not put in simply due to timing constraints.  We
do want to get to it but currently this is not part of cloudstack.

If you don't need SG at all, then you should be able to deploy a share network in advance
zone where vlan is not required at all.
