In some cases there is a need to perform a special access pattern to a disk
backend. This may be done by providing disk reading access to external readers.
In this case there should be the ability to enable/disable the copy-on-read mode
for the disk during VM runtime. 
By the moment, there is no such ability. The patch set adds qmp command to 
enable/disable the copy-on-read mode.

Denis Plotnikov (2):
  block: check for read-only on copy-on-read setting
  qmp: add block-set-copy-on-read command
