So, now MSI-X is in upstream qemu. The issue here is that irqchip in kernel is still unsupported. So here's the plan for qemu-kvm: 1. on next merge from qemu.git to qemu.kvm, virtio net will be broken 2. a quick work-around is to replace this line in hw/apic.c: msix_supported = 1; with if (!kvm_enabled() || !qemu_kvm_irqchip_in_kernel()) msix_supported = 1; 3. once that is merged, I'll add a patch for kernel msi-x that is qemu-kvm specific. 4. Overall it is unfortunate that we still need to add qemu-kvm specific hacks in new code. Is someone working on upstreaming irqchip btw? Comments?
