160 option for the main migration channel, like normal live migration.

166 adding a second migration channel of type ``cpr`` in the channels
171 New QEMU reads the CPR channel before opening a monitor, hence
172 the CPR channel cannot be specified in the list of channels for a
188   * Issue the ``migrate`` command, containing a main channel and
189     a cpr channel.
204 The main incoming migration channel address cannot be a file type.
206 If the main incoming channel address is an inet socket, then the port
211 QEMU blocks waiting to read from the cpr channel before starting its
212 monitor, and old QEMU does not write to the channel until the migrate
214 main migration channel until you issue the migrate incoming command.
216 Example 1: incoming channel
223 HMP cannot specify a CPR channel.  Some QMP responses are omitted for
238                                         -incoming '{"channel-type": "cpr",
252     {"channel-type": "main",
255     {"channel-type": "cpr",
271 accepting the main migration channel.  Again note you must issue the
