The Best Virtual Machine for Linux: KVM vs. VirtualBox vs. QEMU vs. Hyper-V
QEMU, KVM, VirtualBox, and Hyper-V are virtualization technologies that allow you to run multiple operating systems on a single physical machine. While they all serve a similar purpose, there are some key differences between these technologies that are worth noting.
Kernel-based Virtual Machine (KVM) is an open-source virtualization solution built into the Linux kernel. It allows you to create and run virtual machines on a Linux host system using hardware acceleration, providing high performance and low overhead. KVM is often used in production environments due to its stability and reliability.
