When creating the guest on destination with -incoming ip:port in QEMU command
line,
the source code that sets the backlog number as the same as multifd channels
doesn't
get called. So the number of backlog is always 1. It's very easy to cause live
migration
failure, so a bigger number is preferred to reduce the chance of the failure.
