Disks
Each VM must have at least one Disk attached that contains a disk image that the VM will boot from. It can also have additional disks attached for storage purposes.
Each Disk is capped at 4TB.
Each Disk must define a disk storage class. The available Disk storage classes are:
persistent- storage survives node failure and can be detached and reused. Recommended for most use-cases
Boot disks
Each VM must have exactly one boot Disk. It must be configured with a disk image, selected from a set provided by evroc, which defines the VM's operating system image. For each boot Disk, if no size is specified, a default size is used.
Available disk images
The available disk images are:
| Profile Name | Version | Default size |
|---|---|---|
| Minimal Ubuntu | 24.04 | 5 GB |
| Ubuntu | 24.04 | 50 GB |
| Ubuntu | 22.04 | 50 GB |
| Rocky Linux | 9.5 | 50 GB |
| Rocky Linux | 8.10 | 50 GB |
| SLES | 15.6 | 50 GB |
| SLES | 15.5 | 50 GB |
Other disks
A VM can also have one or more additional Disks for storage. These Disks will be unformatted and completely blank, and must be formatted by the user.
See Using Additional Disks for guidance on how to use these Disks once they have been attached to a VM.
