A five-star bake. Worth schmearing, sharing, saving.
Summary
The article introduces QEMU, an open-source emulator capable of emulating complete machines without hardware virtualization support. It explains how QEMU achieves good performance through dynamic translation and can integrate with hypervisors like Xen and KVM. The focus is on emulating CPUs directly to run operating systems designed for specific machines, such as ARMv7 boards.
Key quotes
· 3 pulledQEMU is capable of emulating a complete machine in software without any need for hardware virtualization support.
QEMU can achieve near native performance for CPUs when emulated hardware is provided by the hypervisor.
When QEMU emulates CPUs directly it is capable of running operating systems made for one machine (e.g. an ARMv7 board)
