How does Qemu help here? KVM provides a kernel ABI for operations like "create a virtual CPU" and "run code under virtual CPU". A guest operating system requires not just a CPU but also a complete model of a machine (including UART, network hardware, etc etc). QEMU provides (a) a user interface for the user to configure and start a guest and (b) device models. It would be possible to have a different userspace program which performed the same functions (for example 'kvmtool' can do this for x86), but the standard choice is QEMU, because it is a mature and well supported codebase. -- PMM _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
