TinyKVM presents an innovative approach to virtualization by allowing user processes to run in a lightweight virtual machine (VM) environment built on top of Varnish. This solution aims to enhance security and performance by isolating applications without the overhead of a traditional operating system kernel. Although the concept may seem complex, the essence lies in how TinyKVM manages system calls and VM exits. The technology raises important questions about efficiency—specifically, whether every system call incurs a VM exit overhead or if it operates without typical system calls. The focus on performance and security makes it a compelling topic for developers interested in modern virtualization techniques.
