This patch adds a new QMP command that sets up a domain socket. This
socket can then be used for fast read/write access to the guest's
physical memory. The key benefit to this system over existing solutions
is speed. Using this patch, guest memory can be copied out at a rate of
~200MB/sec,
Summary:
This patch improves Qemu support for virtual machine introspection.
Background:
Virtual machine introspection (VMI) is a technique where one accesses the
memory of a (usually) paused guest. This access is typically used to perform
security checks, debugging, or malware analysis. The

for this we have to reorganize the routing entry to contain

To minimize impact on existing code we introduce an architecture
This set of patches implemets PCI support for the s390 platform.

virtual pci devices conforming to s390 platform constrains.

This patch implements a pci bus for s390x together with infrastructure

MSI/MSI-X notification processing.
From: Frank Blaschka frank.blasc...@de.ibm.com
This patch implements the s390 pci instructions in qemu. It allows
to access and drive pci devices attached to the s390 pci bus.
Because of platform constrains devices using IO BARs are not
supported. Also a device has to support MSI/MSI-X to run on
