Operating System Reinstallation

The Rebuild function of VirtFusion panel lets you completely reinstall your server's operating system in a few clicks, choosing from available templates.

Rebuild deletes all data on disk. Before proceeding, backup everything you want to keep: files, databases, configurations. The operation is irreversible.

• System corrupted and can't access anymore
• Want to change Linux distribution (e.g. Ubuntu to Debian)
• Want fresh system from scratch
• Server compromised and want total reinstall

Process takes 2-5 minutes typically. Server will automatically restart with new OS.

• Access VirtFusion panel
• Select your server
• Go to Options (or Rebuild if direct button)
• Click Rebuild Server
• Choose operating system from menu (distribution and version)
• (Optional) Choose SSH keys to inject automatically
• Set root password (or let it generate random: you'll get email)
• Confirm by clicking Rebuild

Typically available templates include:

Exact list depends on configured templates. Contact support if you need specific distribution not in list.

• Ubuntu 22.04 LTS, 24.04 LTS
• Debian 11, 12
• AlmaLinux 8, 9
• Rocky Linux 8, 9
• CentOS Stream 9
• Fedora (latest versions)
• Windows Server (if enabled in plan)

Once complete, you'll get credentials via email (or you set them during rebuild). Then:

• Access via SSH: ssh root@SERVER_IP
• Update system: apt update && apt upgrade -y
• Follow first access guide

If you want install OS not in templates, use custom ISO:

ISO installation requires interacting via VNC console to complete graphic wizard of OS.

• Go to Media in VirtFusion panel
• Upload or select ISO
• Mount ISO on server
• Go to Options → modify boot order putting CD-ROM before disk
• Restart server
• Access VNC Console to proceed with graphic wizard
