Another serie will come for QEMU. 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.
