Hi, I'm working on the changes discussed in the thread "changing the timing of spice client linking in migration (RHBZ #725009)". In order to be backward compatible with respect to spice-server and qemu we need (1) new qemu calling the old switch_host if the server is old (instead of spice_server_migrate_end)
New qemu can just call spice_server_migrate_start() and check the return value. If it succeeds just go on with seamless migration, otherwise (return value < 0) fallback to switch-host.
(2) new spice-server using the old switch host (and not the new migration mechanism) if qemu is old.
Old qemu which can't handle seamless migration will never ever call spice_server_migrate_start().
