Add an override variable for the DISK file location for each node in a
virtual lab. Introduced the ability to set disk file location for all
nodes in a config file. (was hardcoded to /var/lib/libvirt/images)
This enhancement enables better utilization of the host's disk
resources, allowing for more complex deployments such as
'Distributed Cloud'.
Test plan:
PASS: pylint, flake8, bashate
PASS: Regression for default and madcloud examples
PASS: Able to change what is storage and how many are applied
PASS: Copy default.yaml and modify values of disk directories for nodes
and compare to default.yaml

StarlingX Deployment in Virtualized Environments
A StarlingX system can be installed in a variety of platforms with the following deployment options:
- Standard Controller
- Dedicated Storage
- Controller Storage
- All-in-one
- Duplex
- Simplex
Deployment options uses a variety of configurations based on 3 node identities:
- Controller
- Storage
- Compute
Standard Controller :: Dedicated Storage
The software installation workflow for an initial Ceph-backed block storage on dedicated storage nodes is:
- Controller-0 Installation and Provisioning
- Controller-1 / Compute Host / Storage Host Installation
- Controller-1 Provisioning
- Provider Network Configuration
- Compute Host Provisioning
- Storage Host Provisioning
Standard Controller :: Controller Storage
The software installation workflow for an initial LVM-backed block storage on controller nodes is:
- Controller-0 Installation
- Controller-0 and System Provisioning
- Controller-1 / Compute Host Installation
- Controller-1 Provisioning
- Compute Host Provisioning
All-in-one :: Duplex
The software installation workflow for two combined controller / compute nodes is:
- Controller-0 Installation and Provisioning
- Controller-1 Installation and Provisioning
All-in-one :: Simplex
The software installation workflow for a single combined controller / compute node is:
- Controller-0 Installation and Provisioning
Virtualization Environments
The available virtualization products where StarlingX has been deployed are:
- VirtualBox
- Libvirt/QEMU
Directory: libvirt
Deployment under Libvirt/QEMU uses a set of xml files to define the node identity:
- Controller All-in-one
- Controller
- Compute
- Storage
These nodes are used to create the virtual machines and the network interfaces to setup the StarlingX system:
- Setup Simplex
- 1 Controller
- Setup Duplex
- 2 Controllers
- Setup Controller Storage
- 2 Controllers
- 2 Computes
- Setup Dedicated Storage
- 2 Controllers
- 2 Computes
- 2 Storages
Directory: virtualbox
Deployment under VirtualBox uses a set of configuration files to define the StarlingX system:
- All-in-one Configuration
- Standard Controller Configuration
These configurations files are used to create the virtual machines and the network interfaces from a single script:
- Setup VM
Directory: provision
A set of scripts are provided to automate the provisioning of data interfaces and local storage resources for the compute function for StarlingX Duplex or Simplex.
