Network setup

DNS

We use a local DNS for resolving the pert.edu domain.  The DNS is configured on pertCS01 in the file /etc/dnsmasq.d/pert.edu  When making a change to that file, the dnsmasq process must be restarted with a service dnsmasq restart  This in this file that we'll need to add the IP of the new VM.


All the VM must use 10.0.174.124 as DNS resolver in /etc/resolv.conf  This should be done automatically from the dhclient-eth0.conf file.


IPv4 and IPv6

We prefer to use IPv4 during the training.

Virtual Machines

Architecture SWITCHEngines

The SWITCHengines services is built using the OpenStack cloud middleware.  OpenStack consists of multiple loosely-coupled components.  OpenStack Compute (“Nova”) manages virtual machine instances.  In SWITCHengines, VMs are run under the KVM hypervisor.  OpenStack Networking (“Neutron”, formerly called “Quantum”) manages virtual networks, routers and related functions.  Neutron uses “plugins” that implement these virtual networks using various kinds of underlying equipment.  SWITCHengines uses a configuration with the “ML2” (Modular Layer 2) plugin, Open vSwitch (OVS) as the internal forwarding mechanism, and VxLAN as an encapsulation mechanism to implement “tenant” networks isolated from each other.

Virtual Machines (VM)

We have the following machines available for the training, from SWITCH.
