Cloud: Compute Node Setup: Difference between revisions

Latest revision as of 20:58, 29 December 2021

UPDATE: this page is deprecated, as it is for the old cloud which used OpenStack. We are now using CloudStack instead.

Machine setup

Disk configuration

A block device with lost of disk space (to be mounted at /var/lib/nova/instances)

Networking configuration

Do not register the IPv6 address in DNS. This may cause issues with OpenStack services.

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))

Fix ebtables

update-alternatives --config ebtables

and choose "ebtables-legacy". This is necessary to work around missing features in ebtables-nft.

`/etc/sysctl.d/10-ipv6.conf`

# Disable autoconf
net.ipv6.conf.all.autoconf=0
net.ipv6.conf.default.autoconf=0

# Stop accepting router advertisments
net.ipv6.conf.all.accept_ra=0                                                                       
net.ipv6.conf.default.accept_ra=0

# Do not use temporary addresses
net.ipv6.conf.all.use_tempaddr=0                                                                    
net.ipv6.conf.default.use_tempaddr=0

`/etc/network/interfaces`

Configure the switch port with VLAN 529 as the untagged VLAN, and VLANs 134 and 425 as the tagged VLANs.

# Management interface

iface $INTERFACE inet static
   address        172.19.168.XX
   netmask        255.255.255.224
   gateway        172.19.168.1

iface $INTERFACE inet6 static
   address fd74:6b6a:8eca:4902::XX
   netmask 64

Compute service

Prerequisites

debian.csclub APT repository configured

Installation

Configure virtualization

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

Install Nova Compute

Based on the official OpenStack document:

sudo apt install nova-compute neutron-linuxbridge-agent

Now configure:

`/etc/nova/nova.conf`
