This patch implements parallel live migrations for libvirt driver. It is achieved through introduction of new configuration parameter `live_migration_parallel_connections`. This allows to eliminate bottleneck on live migration speed by establishing multiple connections for memory transition, thus leveraging multi-threaded behavior in QEMU.

Implemented parallel live migrations for libvirt driver, which can be
|
|
enabled by defining ``[libvirt] live_migration_parallel_connections``
|
|
to a value higher than 1. By default parallel migrations are not used to
|
|
preserve existing behavior. Also note that QEMU prior to 10.1.0 was not
|
|
able to support multifd with postcopy migrations, so enabling these two
|
|
features together on older QEMU versions is disallowed.
