This patch modifies virtio-console to use virtio_config_val() instead of a 'if(virtio_has_feature()) vdev->config->get()' construct to retrieve optional values from the config space.

Hello, These patches are an initial attempt at supporting hibernation for virtio drivers. The default configuration of event_index=on doesn't work; i.e. restore from a hibernated image only works if the devices have event_index support turned off. I have not yet dug into this, but is most likely due to some state not being sync'ed. This could be related to the hack that is patch 3.

As multi-queue nics were commonly used for high-end servers, current single queue based tap can not satisfy the requirement of scaling guest network performance as the numbers of vcpus increase. So the following series implements multiple queue support in tun/tap. In order to take advantages of this, a multi-queue capable driver and qemu were also needed. I just rebase the latest version of
