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.

Hi, These patches add support for S4 to virtio (pci) and all drivers. For each driver, all vqs are removed before hibernation, and then re-created after restore. Some driver-specific uninit and init work is also done in the freeze and restore functions. All the drivers in testing work fine: * virtio-blk is used for the only disk in the VM, IO works fine before and after. * virtio-console:

Hi, These patches add support for S4 to virtio (pci) and all drivers. Michael saw some race in virtio-net module removal which will need a similar fix for the freeze code as well. I'll update the virtio-net patch with that fix once the fix is settled upon and applied. For each driver, all vqs are removed before hibernation, and then re-created after restore.
