  • 0 Ratings

Purpose

This article provides information about the requirement to have Metadata service and the Management Network to be separated.

Resolution

VMware recommends to use the default VMware Integrated Openstack configuration when deploying VMware Integrated Openstack. The default configuration for VMware Integrated Openstack is to use the same network for the Metadata service and the Management network.

There are some configurations that require a separate network for both the Metadata service and the Management network.
 
 
  1. When deploying Openstack, the eighth step of the deployment is Configure Neutron Networking as described in
    Deploy a new OpenStack  Instance by Using the Integrated OpenStack Manager.
  2. The use the same Port Group from metadata service option is selected by default. If you want to use a different Port Group, select use a different Port Group for metadata service option at this stage and then enter the Port Group, IP, Netmask and Gateway for this service.

    When enabling this option, it is the Administrators responsibility to ensure that network communication exists between the VIO Management Network and the Metadata service network. This implies that the network design has a reliable route between the two Port Groups. If there is not a reliable network route between the two Port Groups, the Metadata service might fail.
