Hi all:
 
    When use multi-node installation with vlan mode, the vlan configuration is in switch or in nova control node? And what's the vlan configuration process?
 
    I read this article : http://dodeeric.louvrex.net/?p=225
 
    ================begin====================
In the VLAN network mode, each project is given a specific VLAN/subnet. We will configure three VLANs/subnets (feel free to create much more):
- VLAN: 1 — Subnet: 10.0.1.0/24 — Bridge name: br_vlan1:# nova-manage network create 10.0.1.0/24 1 256
- VLAN: 2 — Subnet: 10.0.2.0/24 — Bridge name: br_vlan2:# nova-manage network create 10.0.2.0/24 1 256
- VLAN: 3 — Subnet: 10.0.3.0/24 — Bridge name: br_vlan3:# nova-manage network create 10.0.3.0/24 1 256
    =================end===================
 
  It's seem like configure vlan in nova control node?
 
  If there are two switch: one is for public and another is for private, both public and private switch need support vlan 802.1q? Or just private switch is need support vlan 802.1q?
 
  thanks
