Please introduce a CONFIG_VHOST_SCSI and #ifdef appropriate sections in hw/virtio-pci.c. CONFIG_VIRTFS does the same thing. > +static Property vhost_scsi_properties[] = { > + DEFINE_PROP_BIT("ioeventfd", VirtIOPCIProxy, flags, VIRTIO_PCI_FLAG_USE_IOEVENTFD_BIT, true), This flag makes QEMU's virtqueue handling use ioeventfd. Since the vhost-scsi.c takes over the guest/host notifiers, we never do QEMU virtqueue processing and the "ioeventfd" flag has no real meaning.
