Pre-Virtualization: Soft Layering for Virtual Machines
Overview Para-virtualization ties a guest operating system and a hypervisor together, which restricts the system architecture; e.g., when Linux uses the Xen API, Linux is unable to run on alternative hypervisors such as VMware, Linux itself, or a security kernel such as EROS. Furthermore, the lock-in obstructs evolution of its own para-virtualization interface - virtual machines provide the vital ability to run obsoleted operating systems alongside new operating systems, but para-virtualization often lacks this feature, requiring all concurrent instances to be the hypervisor's supported version. Even general purpose operating systems have weaker restrictions for their applications.
