Install a Compute Node

Before starting...

If you want to deploy a Compute Node with a dedicated Network Interface for the storage traffic, then you need three Network Interfaces and add this configuration manually in the /etc/network/interfaces file:

auto eth1
iface eth1 inet static
        address STORAGE_IP
        netmask 255.255.255.0
        network STORAGE_NETWORK
        broadcast STORAGE_BROADCAST_ADDRESS
        gateway STORAGE_GATEWAY

You can reboot or simply execute this command:

ifup eth1

Configure the Compute Node

The component needs to pass these 4 steps to install it successfully.

Check hardware requirements

The Smart Installer checks if the hardware supports Openstack. Please review the System requirements before continuing.

Check software requirements

The Smart Installer checks if the operating system supports Openstack. Please review the System requirements before continuing.

Warning
Ignore messages about an outdated version of the distro.

Configure Network Topology

The Compute node can use three different networks:

Openstack Management Network
Storage Network
Service Network
Choose which network card will be used for each network. Keep in mind that Service Network cannot share the Network Interface with any other Network. Management and Storage Networks can share the same NIC.

Configure Compute Parameters

The Compute Node inherits all the global parameters to work. So, if you need to modify a parameter keep in mind that the global parameter will be unaltered. We strongly recommend not to modify any parameter given by default if you are not an expert.
If your system has virtualization extensions then you can choose the KVM hypervisor or QEMU emulator. If you don't have virtualization extensions (running inside a virtualization platform for example) then you only can use QEMU emulator.
