From dc15541d5998e08001194b10863fe63a916263c8 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 17 Jan 2018 09:07:00 +0000 Subject: block: add block_set_io_throttle virtio-blk-pci QMP example The block_set_io_throttle command can look up BlockBackends by the attached qdev device ID. virtio-blk-pci is a special case because the actual VirtIOBlock device is the "/virtio-backend" child of the PCI adapter device. Add a QMP schema example so clients will know how to use block_set_io_throttle on the virtio-blk-pci device. The alternative is to implement some sort of aliasing for qmp_get_blk() but that is likely to cause confusion and could break future use cases. Let's not go there.
