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