It's a huge variety of operating systems available to you. All OS templates were previously tested on a VPS to ensure them as fully operational.

Bear in mind that our OS templates are mostly updated by SolusVM. As soon as SolusVM launches new templates for their OS templates, we'll ensure you have those available.

¹ Customer needs to bring their own license or, after expiration, Microsoft will shutdown Windows every 60 minutes.
² Server Core is usable for plans with 2-4GB RAM and at least 30GB (ex: CentralVPS-2048). Server with Desktop Experience can only be used on 4GB or more of RAM (ex: ExtraVPS-4096). Not available on plans under 2GB RAM.
³ Arch Linux is provided only for Arch-dependent workloads - while working, it has shown slow disk performance when virtualized over KVM (around 10% of total performance, HDD-equivalent on an NVMe). Proceed with caution.
⁴ This operating system doesn't natively support cloud-init, which is essential for virtualization. It's still possible to use ISOs to deploy local packages. Proceed with caution.

What about the Custom ISOs on MultiVPS?

Custom ISOs can be used on any VPS package, as long as they are uploaded from the user. This functionality is preferably accessible through the MultiVPS Portal (portal.cfld.uk), where uploaded ISOs can be seen and booted from.

Ensure that the relevant packages for your VM are installed - if your system logs some errors, ensure you have cloudinit/v2 packages installed on your personalized VPS.
