Cover letter [Qemu-devel] [PATCH v0 0/2] enable/disable copy-on-read via qmp
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.
