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 arch_init.c | 6 + hw/ide/qdev.c | 8 ++- hw/pc_piix.c | 40 +++++--- hw/pci.c | 6 + hw/xen.h | 31 ++++++ hw/xen_common.h | 58 +++++++++++ qemu-config.c | 12 ++ xen-all.c | 304 +++++++++++++++++++++++++++++++++++++++++++++++++++++-- xen-stub.c | 5 + 9 files changed, 447 insertions(+), 23 deletions(-) -- Julien Grall
