Iglesias" This series breaks out parts of the ARM PVH support into an abstract machine that other targets can reuse.. There's a bit of refactoring and some bug-fixes along the way. Finally we add a new x86 xen-pvh machine. The corresponding changes in Xen for PVH x86 are work in progress (by Xenia Ragiadakou). You can find a current version here: https://github.com/edgarigl/xen/tree/edgar/virtio-pvh-upstream I've briefly described the steps to run Xen PVH x86 guests here (including example guest kernel config, xl.cfg and xl command-lines): https://github.com/edgarigl/docs/blob/master/xen/pvh/xenpvh-x86.md Cheers, Edgar ChangeLog: v1 -> v2: * Use an abstract PVH Machine to share code between arch specific PVH machines. This allows more sharing than a using a device component. * Add comments describing our PCI INTX support. * Allow the PVH target specific implementation to provide PCI INTX delivery via class methods. * Clarify use of mc->max_cpus in comments. * Use GUEST_MAX_VCPUS mc->max_cpus on ARM. * Use HVM_MAX_VCPUS mc->max_cpus on x86. * pvh-common: Directly use s->cfg. members when creating gpex. * pvh-common: Clarify use of pci-ecam-size in comments. * x86/xen-pvh: Create smp.max_cpus nr of dummy cores (not smp.cpus). * x86/xen-pvh: Replace static array holding dummy cores with a dynamic one. * Move stubbed Xen/ARM functions from hw/arm/xen_arm.c into xen-stubs.c Edgar E.
