The loading time of a VM is quite significant when its virtio devices use a large amount of virt-queues (e.g. a virtio-serial device with max_ports=511). Most of the time is spend in the creation of all the required event notifiers (ioeventfd and memory regions). This patch pack all the changes to the memory regions in a single memory transaction.
