Installing and Running KVM on Ubuntu 14.04 Part 2
In part 1 of the series I covered basic machine set up and preparation. In this second part of the series about setting up KVM on Ubuntu 14.04 I cover setting up the network. Setting up the network can seem quite daunting but a basic KVM install doesn’t actually require much network set up.
Understanding TUN TAP Interfaces
As I mentioned in the previous article Understanding Bridges, Linux and most other operating systems have the ability to create virtual interfaces which are usually called TUN/TAP devices. This article will discuss those devices with particular focus on how they are used in OpenStack.
Understanding Bridges
