Can I create or upload custom pre-configured images?

Yes, you can upload your own image to the immers.cloud platform: either from a local file or via a direct URL from an external source.

To do this, go to Storage → Images in the left-hand menu and click Create.

In the window that appears, specify:

1. Image name;
2. Disk format;
3. Source: upload a file from your computer or paste a direct link in the URL field.

Once you click Create, the image upload will begin.

Note: If you provide a URL, the image will be downloaded at the moment you create a virtual server.

Important: When creating a server from an ISO image, the entire contents of the ISO are written directly to the server’s primary disk, which can lead to unexpected system behavior.

We recommend:

• Creating a server from a ready-made Linux image (e.g., Ubuntu);
• Attaching your ISO as a second disk using Rescue mode (via the “Actions” menu).

This approach lets you install an OS from the ISO just like using a physical installation disc—ensuring a clean and predictable setup.

Technical Requirements for Custom Images

For your image to work correctly on our platform, the following conditions must be met:

Linux Images

1. Сloud-init must be installed and configured (to auto-set up networking, users, and SSH keys on first boot);
2. SSH access must be enabled (SSH server running, and at least one user created with password or key-based login).

Windows Images

• VirtIO drivers must be installed (for proper virtual network and disk functionality);
• Cloudbase-Init must be installed and configured (Windows equivalent of cloud-init);
• RDP access must be enabled (Remote Desktop turned on, and a user with a password and login rights created).

If these requirements aren’t met, you may need to manually configure users, drivers, and access after launching the server.
