Cloud: Compute Node Setup

Configuring a new compute node

NOTE: These instructions are a WIP

Machine setup

Networking configuring

We will be using 2 interfaces on the machine:

• 1gbps for management (VLAN 529 (CSC Cloud Management))
• 10gbps for VMs (VLAN 134 (MSO), 425 (CSC Cloud))

/etc/network/interfaces

Compute service

Prerequisites

• debian.csclub APT repository configured

Installation

Configure virtualization

1. Allow syscom access to libvirt.

   /etc/polkit-1/localauthority/50-local.d/libvirt.pkla

   [Allow syscom to libvirt]
   Identity=unix-group:syscom
   Action=org.libvirt.unix.manage
   ResultAny=yes

2. sudo apt install qemu qemu-kvm libvirt-bin bridge-utils

Install Nova Compute

From:

• https://docs.openstack.org/ocata/install-guide-ubuntu/nova-compute-install.html
• https://docs.openstack.org/ocata/install-guide-ubuntu/neutron-compute-install.html

sudo apt install nova-compute neutron-linuxbridge-agent

Now configure:

/etc/nova/nova.conf
