Virtual Machine
To help contestants familiarize themselves with the software environment in advance, an IOI 2026 virtual machine image will be provided. The VM is intended solely for practice purposes — the actual contest computers will run the operating system natively, not inside a virtual machine. Therefore, please avoid reporting issues that are caused by virtualization-specific behavior or performance limitations of the VM.
