When you run a command to start a KVM-accelerated VM, you are technically using QEMU to talk to the /dev/kvm interface. This collaboration allows for advanced features like , where a running VM is moved from one physical server to another without downtime. Conclusion
acts as the "brawn," handling the CPU and memory management within the kernel.
acts as the "brains" and "interface," providing the I/O device emulation (disk drives, network cards, USB controllers) and the management tools to start and stop the VMs.
QEMU is a hosted virtual machine monitor that performs hardware virtualization. Its primary strength is : it can mimic various hardware architectures (like ARM, SPARC, or x86) on a different host machine. However, pure software emulation is slow because every instruction must be translated by the CPU. To speed things up, QEMU can use an "accelerator" to execute instructions directly on the host hardware. This is where KVM comes in. KVM: The Performance Engine
