Obsolete:InstallInstructions/Nova

= Installation =

Before you install, you need to make some choices on your setup. The key questions you need to answer are:


 * Do you want to install from source or from packages (one of the releases or proposed releases)?

If you want to install for development, or to try out the latest bleeding edge of one of the projects, consider installing that code from source. If you want to "see how it works" or run a proof of concept, install the release from packages.


 * How many physical hosts are you using to set up the environment?

In a development environment, many people are putting everything they can into an All-In-One environment. If you're setting up a proof of concept, you may want to install the components on multiple systems.


 * What kind of network configuration do you want to use?

OpenStack Compute supports two modes of Networking for the virtual machines - Flat networking and VLAN networking. VLAN based networking requires that you have a VLAN capable managed switch that you can use to setup VLANs for your systems. Flat Networking uses linux ethernet bridging (br100) to connect multiple compute hosts together when you have the --flat_network_bridge flag set in your nova.conf.


 * What hypervisor do you want to use?

Nova supports many of the leading hypervisors, including KVM (and several others using libvirt), XenServer/XCP and ESXi.
