Linux-vServer / KVM

Comparison of Linux virtualized server and KVM-based virtualisation

This section looks at the two root server techniques used by Linux-vServer and KVM, highlighting their key differences and common features.

As a full virtualisation solution, KVM offers the feature set of a dedicated server. Linux-Root Server, on the other hand, is based on "container virtualisation", whereby users cannot install their own kernels (for example)
