Prerequisites
Cloud access
The usual prerequisite is to have an account on one of the supported OpenStack cloud providers. As the OSISM Testbed also virtualizes systems itself, the OpenStack cluster should provide the capabilities for nested virtualization.
It is not part of this guide to describe the registration with the individual cloud providers. Please contact the respective cloud provider for this.
| Provider | Product | Profile name | Note |
|---|---|---|---|
| OSISM | REGIO.cloud | regiocloud | |
| OSISM | REGIO.cloud | regio-fast | boot from NVMe SSD backed volumes |
| Cleura | Cleura | cleura | |
| FUGA | Fuga Cloud | fuga | |
| HuaweiCloud | HuaweiCloud | huaweicloud | |
| OVH | OVH | ovh | |
| T-Systems | OpenTelekomCloud | otc | |
| plusserver | pluscloud open | pluscloudopen | |
| plusserver | pluscloud SCS Test | gx-scs | |
| noris network | Wavestack | wavestack | |
| artcodix | CNDS Cloud | artcodix |
For each cloud provider listed in the table, a predefined profile is available in the
terraform/environments directory. This profile contains the name of the public
network, which flavors to use, etc.
Here is an example from the profile for REGIO.cloud.
flavor_manager = "SCS-4V-16-50"
flavor_node = "SCS-8V-32-50"
volume_type = "ssd"
image = "Ubuntu 22.04"
image_node = "Ubuntu 22.04"
public = "public"
availability_zone = "nova"
volume_availability_zone = "nova"
network_availability_zone = "nova"

The OSISM Testbed requires at least the following project quota when using the default flavors:
| Resource | Quantity | Note |
