What is QEMU?
QEMU is an open-source hypervisor that allows users to run multiple virtual machines (VMs) on a single physical host. It is widely used for virtualization, emulation, and testing purposes. QEMU supports a wide range of architectures, including x86, ARM, and PowerPC, making it a versatile tool for developers, testers, and administrators.
QEMU’s key strength lies in its ability to provide a sandboxed environment for testing and development. This allows users to safely test new software, configurations, and operating systems without affecting the host system. Additionally, QEMU’s support for snapshots and rollback features provides a high degree of flexibility and recoverability.
