"VUOS is a Virtual Operating System implemented at user space. Currently it implements about 150 Linux-compatible system calls providing support for a wide range of applications. Each process or even each thread in VUOS can see a different execution environment: file system contents, networking, devices, user ids etc. The main idea behind VUOS is that it is possible to give processes their own "view" using partial virtual machines.

VUOS is a different perspective on namespaces, anykernels and related concepts.

A partial virtual machine intercepts the system call requests and operates like a filter: system call can be forwarded to the kernel of the hosting system or processed by the partial virtual machine hypervisor."
