1 .. _s390x-System-emulator:
6 QEMU can emulate z/Architecture (in particular, 64 bit) s390x systems
7 via the ``qemu-system-s390x`` binary. Only one machine type,
8 ``s390-ccw-virtio``, is supported (with versioning for compatibility
11 When using KVM as accelerator, QEMU can emulate CPUs up to the generation
12 of the host. When using the default cpu model with TCG as accelerator,
13 QEMU will emulate a subset of z13 cpu features that should be enough to run
14 distributions built for the z13.
19 QEMU will not emulate most of the traditional devices found under LPAR or
20 z/VM; virtio devices (especially using virtio-ccw) make up the bulk of
21 the available devices. Passthrough of host devices via vfio-pci, vfio-ccw,
22 or vfio-ap is also available.
