QEMU is a machine emulator and virtualizer that can run guest operating systems and software for different processor architectures, with hardware-acceleration options and command-line controls for developers, testers, and virtualization systems.
Developers testing operating systems and alternative architectures
Configuration can be complex. Software emulation can be much slower than native execution.

QEMU is a useful option for developers testing operating systems and alternative architectures. Run a small guest with explicit memory, disk, and network settings before exploring more elaborate virtual hardware. Start with a small, representative task so you can check the results before extending the setup.
Match acceleration options to the host architecture and keep guest disk images backed up separately from temporary snapshots. Consider the practical trade-off: configuration can be complex.
