Hi, V2: * Revert odd changes in migrate() * Add short description for socket_send_fds() and remove ifdef WIN32 as it's not needed This series is a continuation of the previous two: * migration: Fix handling fd protocol * Add 'inline-fd:' protocol for migration It's about such use case: 1. Target VM: exec ...,-incoming defer 2. Target VM: getfd("fd-mig") 3. Target VM: migrate-incoming("fd:"fd-mig") 4. Source VM: getfd("fd-mig") 5. Source VM: migrate("fd-mig") Currently, it's not possible to do the step 3, because for incoming migration "fd:" protocol expects an integer, not the name of fd.
