[PATCH 0/5] qemu: add virtio-blk queue-size option

[Hiroki Narukawa]

This is resubmit of "qemu: add virtio-blk queue-size option" after following the review.

The option "queue-size" in virtio-blk was added in qemu-2.12.0, and default value increased from qemu-5.0.0.
However, increasing this value may lead to drop of random access performance.
This is configurable value, so we want to use it via libvirt.

Hiroki Narukawa (5):
  qemu: Make disk-virtio-queues tests use DO_TEST_CAPS_LATEST
  qemu: add disk queue count ABI stability check
  qemu: add queue_size option to disk
  qemu: add QEMU_CAPS_VIRTIO_BLK_QUEUE_SIZE capability
  qemu: add virtio-blk queue-size option
