[libvirt] [PATCH 4/8] qemu: Make migration params usable outside migration

[Jiri Denemark]

So far migration parameters were changed only at the beginning of
migration mostly via an automatic translation from flags and typed
parameters. We need to export a few more functions to support APIs which
may set migration parameters while migration is already running.
