[Qemu-devel] [QEMU][RFC PATCH 0/6] QEMU disaggregation

[Julien Grall]

This patch series concerns QEMU. Another serie has already came for Xen.

As we discussed on Xen/QEMU mailing list
(http://marc.info/?l=qemu-devel&m=133042969527515), I have worked on multiple
QEMU support for one domain.

QEMU must registered all IO ranges (MMIO and PIO) and PCI that it's want's to
use to allow multiple QEMU.

Each QEMU will handle a subset of the hardware. It will retrieve its
configuration with XenStore.

Both of these patch series (one for Xen, the other Xen) are not complete,
and it breaks some parts of Xen ...

The purpose of these series is to start a discussion on how to implement
multiple ioreq server on Xen and QEMU.

Julien Grall (6):
  option: Add -xen-dmid
  xen: Add functions to register PCI and IO in Xen
  memory: Add xen memory hook
  xen-pci: Register PCI in Xen
  xen-io: Handle the new ioreq type IOREQ_TYPE_PCI_CONFIG
  xen: handle qemu disaggregation
