ISOs let you install operating systems that aren’t in the OS template catalog. Upload an ISO once at the project level, then choose it under Operating System → ISOs when creating a VM.
The page lists every ISO in the current project, with a Search ISOs… box and a Refresh button. The empty state shows No ISOs Found with an Add ISO call-to-action.
Click Add ISO (top-right or the empty-state button). The ADD ISO dialog opens with the subtitle Upload from a remote URL (up to 10 GB).
In ISO NAME, give the image a clear, human-readable label.
Example: Ubuntu 24.04 LTS
This is the name you’ll see in the ISOs list and in the VM deployer’s ISOs tab.
In REMOTE URL, paste the public URL where the ISO can be downloaded.
Example: https://releases.ubuntu.com/24.04/ubuntu-24.04.iso
The dialog reminds you of the upload requirements:
If your image lives behind authentication, host it on a public bucket (such as Object Storage) or generate a signed URL that doesn’t require headers.
The VM boots from the ISO. Open the Console to step through the installer, partition the root disk, and finish the install.
From the ISOs list:
Deleting an ISO removes it from project storage. VMs already installed from the ISO are unaffected — the install lives on the VM’s own root disk.
For a custom Linux ISO to boot cleanly under KVM, verify before uploading:
/dev/vda.For Windows ISOs, plan to install virtio drivers from the Windows guest tools ISO during setup.
Add ISO button is disabled
Both ISO NAME and REMOTE URL are required. The URL must start with http:// or https://.
Download fails or stalls The URL must be publicly reachable from IBEE infrastructure. Check the URL in a browser; if it requires authentication, redirects to a login page, or rate-limits unauthenticated downloads, host the ISO somewhere that doesn’t.
Image rejected as “unsupported format”
Only .iso files are accepted. Cloud images in .qcow2, .img, or .vmdk are not — for those, see Custom images (snapshot/backup paths instead).
ISO won’t boot Open the Console and watch the boot output. Most failures are missing virtio drivers or a bootloader pointing at the wrong device.
