Description

The proposed patch handles a typo in the VM metadata parser.
Also, when the target is a vd(virtio-blk) disk:

  • Check if there are iothreads defined for the domain.
  • If there is speciffic thread id defined for the disk
  • If no - the optional default attach virtio iothread id
  • check the values: use the max iothreads if the suggested iothread is bigger than the defined iothreads, or do not define if the suggested iothread is 0 or less.
