[Xen-devel] [QEMU][RFC V2 00/10] QEMU disaggregation in Xen environment.

[Julien Grall <julien.grall@xxxxxxxxxx>]

Hello,

This patch series only concerns QEMU. Another serie will come for Xen.

I'm currently working on QEMU disaggregation in Xen environment. The
goal is to be able to running multiple QEMU for a same domain
(http://lists.xen.org/archives/html/xen-devel/2012-03/msg00299.html).

I have already sent a version of patch series few months ago:
    - QEMU: https://lists.gnu.org/archive/html/qemu-devel/2012-03/msg04401.html
    - Xen: http://lists.xen.org/archives/html/xen-devel/2012-03/msg01947.html
With the different feedbacks, I have improved both QEMU and Xen modifications.
As before, I will sent two patch series, one for QEMU the other for Xen.

Modifications between V1 and V2:
    - introduce new machine options
    - use memory listener to avoid Xen specific code in QEMU core
    (depends of "[PATCH V5 0/8] memory: unify ioport registration" patch series)
    - implement disaggregation
    - add wrapper for older Xen version

Julien Grall (10):
  xen: add new machine options to support QEMU disaggregation in Xen
    environment
  xen: modify QEMU status path in XenStore
  xen: add wrappers for new Xen disaggregation hypercalls
  xen-hvm: register qemu as ioreq server and retrieve shared pages
  xen-memory: register memory/IO range in Xen
  xen-pci: register PCI device in Xen and handle IOREQ_TYPE_PCI_CONFIG
  xen: specify which device is part of default devices
  xen: audio is not a part of default devices
  xen-memory: handle node "device_model" for physical mapping
  xen: emulate IDE outside default device set
