[Qemu-devel] [QEMU][RFC V2 01/10] xen: add new machine options to support QEMU disaggregation in Xen environment

[Julien Grall]

    - xen_dmid: specify the id of QEMU. It will be used to
    retrieve/store information inside XenStore.
    - xen_default_dev (on/off): as default devices need to be create in
    each QEMU (due to code dependency), this option specifies if it will
    register range/PCI of default device via xen hypercall.
    (Root bridge, south bridge, ...).
    - xen_emulate_ide (on/off): enable/disable emulation in QEMU.
