|     hw/virtio-net: disable multiqueue by default
|
|     The new multiqueue feature adds fields to the virtio device config, which
|     breaks Windows guests. Disable the feature by default until the Windows
|     drivers are fixed.

  '12:13' would be wrongly matched as a float.

'.' matches an arbitrary char, '\.' matches a dot.

Previously each image check paused and unpaused the VM. With this
patch it pause vm, checks all images and unpause again (if required).

Additionally this processes the all remaining images in case of
failure thus image check failure won't prevent other images to be
checked/deleted (in postprocess).
