  16. Paravirtualization: Xen • Different hardware components not fully emulated. It only organizes the usages->near-native performance • Layout of a Xen based system: Privileged host system(Dom0) and unprivileged guest systems (DomU) • DomU are working cooperatively • Guest and host OS has to be adapted to XEN (Kernel-Patch), but not the applications
