Description

There are three possible status: BDRV_IOS_OK (no error), BDRV_IOS_ENOSPC (no space error) and BDRV_IOS_FAILED (any other error). Three types of interface: virtio-blk-pci, ide, virtio-scsi. QMP command: {"execute": "query-block"}
Steps:
{"execute": "query-block"}
--- Reproduced with qemu-kvm-0.12.1.2-2.209.el6.x86_64
Actual Result:
No "io-status" returned by query-block.
