Vendor minimums are not a complete capacity plan. Installation media, package downloads, updates, applications and snapshots need storage as well. Our package recommendations therefore provide more room than a bare minimum installation.
Step by step
- Debian recommends 1 GB RAM and 4 GB disk without a desktop. For a simple server installation the smallest KVM packages provide 1 GB RAM and 16 GB SSD. This is not a recommended desktop package.
- For a desktop, Debian recommends 2 GB RAM and 10 GB disk. For Xfce we suggest at least 2 GB RAM and 32 GB SSD; for GNOME, KDE or multiple applications, consider 4 GB RAM and 48 GB SSD.
- Automatic Ubuntu Server installation requires at least 25 GB SSD in the panel as a practical lower bound. The 2 GB package with 32 GB SSD accommodates this; additional services can need more RAM and disk.
- Ubuntu Desktop 26.04 and the current desktop release recommend 6 GB RAM and at least 25 GB free disk space. The panel’s 8 GB RAM / 80 GB SSD package fits that recommendation. Older versions may have different RAM recommendations.
- An uploaded ISO remains on the server. For example, a 10 GB OS plus a 6 GB ISO already uses about 16 GB before further updates and data. Choose a larger package or remove media you no longer need.
- When replacing installation media, the old ISO and new upload temporarily need space at the same time. With the VM stopped, use the file manager to remove unnecessary old ISOs before uploading.
- Snapshots share available storage with the VM and do not replace external backups. Large databases, mods, videos or Docker images need space in addition to these OS recommendations.
- Automatic installation permits Debian only from 8 GB SSD and Ubuntu from 25 GB SSD. This protects the installation process; it is not a recommendation for every subsequent workload.
- Check df -h inside the guest before major updates. The panel counts server files such as the virtual disk and ISO; the guest displays its partitions. Filesystem metadata and partitioning use some space too.
- Choose the right package in the configurator and check the price for your selected duration. Dedicated IPs and optional extras are listed separately at checkout. Existing servers keep their stored resources until you explicitly change them.

The OS and desktop fit the RAM allocation, with room left after installation and ISO upload for updates and applications. Official requirements are linked below.
Important
These recommendations cover typical Linux use rather than every application. Firmware, CPU architecture and drivers must also match the ISO. A larger package does not provide missing UEFI/TPM support.
