* Split the network setup/teardown bits into their own scripts so you can shoot yourself in the foot with intention rather then unexpectedly. * Cowardly refuse to configure a network if the first interface name exists * Change the default bridge name to stxbr * Make the network variables all configurable via the environment * Don't make assumptions about where ISOIMAGE is located * Include a basic doc that outlines the differences from existing installation steps.

StarlingX Deployment on Libvirt
This is a quick reference for deploying StarlingX on libvirt/qemu systems. It assumes you have a working libvirt/qemu installation for a non-root user and that your user has NOPASSWD sudo permissions.
Overview
We create 4 bridges to use for the STX cloud. This is done in an initial step separate from the VM management.
Depending on which basic configuration is chosen, we create a number of VMs for one or more controllers and storage nodes.
These scripts are configured using environment variables that all have built-in defaults. On shared systems you probably do not want to use the defaults. The simplest way to handle this is to keep an rc file that can be sourced into an interactive shell that configures everything. Here's an example:
export CONTROLLER=madcloud
export COMPUTE=madnode
export BRIDGE_INTERFACE=madbr
export INTERNAL_NETWORK=172.30.20.0/24
export INTERNAL_IP=172.30.20.1/24
export EXTERNAL_NETWORK=192.168.20.0/24
export EXTERNAL_IP=192.168.20.1/24
There is also a script cleanup_network.sh
that will
remove networking configuration from libvirt.
Networking
Configure the bridges using setup_network.sh
before
doing anything else. It will create 4 bridges named stxbr1
,
stxbr2
, stxbr3
and stxbr4
. Set
the BRIDGE_INTERFACE environment variable if you need to change stxbr to
something unique.
The destroy_network.sh
script does the reverse, and
should not be used lightly. It should also only be used after all of the
VMs created below have been destroyed.
Controllers
There are two scripts for creating the controllers:
setup_allinone.sh
and
setup_standard_controller.sh
. They are operated in the same
manner but build different StarlingX cloud configurations. Choose
wisely.
You need an ISO file for the installation, these scripts take a name
with the -i
option:
./setup_allinone.sh -i stx-2018-08-28-93.iso
And the setup will begin. The scripts create one or more VMs and
start the boot of the first controller, named oddly enough
controller-0
. If you have Xwindows available you will get
virt-manager running. If not, Ctrl-C out of that attempt if it doesn't
return to a shell prompt. Then connect to the serial console:
virsh console madcloud-0
Continue the usual SterlingX installation from this point forward.
Tear down the VMs using destroy_allinone.sh
and
destroy_standard_controller.sh
.
