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.
