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

Distributed Virtual Switch
2 components:
- Virtual Supervisor Module – Control Plane
- Virtual Ethernet Module - Data Plane
• VSM and VEM uses L3 mode of communication
• VSM can be a Virtual Appliance (VM) or a Physical Appliance (N1110)

• Port-profiles – templates to configure network and policy parameters for multiple VMs in one shot.
• Rich feature-set (aligns with Physical switches)
Eg: ACL, QoS
Netflow, SNMP
Port-security, PVLAN, DHCP snooping, DAI, IPSG
VXLAN
• Multi-hypervisor support
ESX (VMWare), Hyper-V (Microsoft), KVM (Linux)

• VEM on KVM Hypervisor
• Openstack for creating, managing Virtual Machines
• Puppet for installing VEMs
• VXLAN-VLAN Gateway : to bridge traditional networks to virtual networks

• 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
