1. vMotion moves VMs across
physical ports—the network
policy must follow vMotion
(across racks, PODS, DCs)
2. Must view or apply
network/security policy to
locally switched traffic
3. Need to maintain segregation
of duties while ensuring
non-disruptive operations

• Cisco OpenStack Installer (Cisco OSI) simplifies the OpenStack
installation process
• Configure an initial Build server outside the Openstack cluster
environment, After that it is used as an out-of-band automation and
management workstation to bring up, control, and reconfigure (if
necessary) the nodes of the OpenStack cluster.
• This build server primarily functions as a Puppet server for software
deployment and configuration management onto the OpenStack cluster,
as well as a Cobbler installation server to manage the PXE boot used for
rapid bootstrapping of the OpenStack cluster.
• VSM, VEM and VxLAN-VLAN Gateway Installation
