When IOMMU is enabled, the ring addresses set by the VHOST_USER_SET_VRING_ADDR requests are guest's IO virtual addresses, whereas Qemu virtual addresses when IOMMU is disabled. When enabled and the required translation is not in the IOTLB cache, an IOTLB miss request is sent, but being called by the vhost-user socket handling thread, the function does not wait for the requested IOTLB update. The function will be called again on the next IOTLB update message reception if matching the vring addresses.
