Description of problem:
None of the QEMU migration transports have native support for encryption. As such apps/users needing security must tunnel the QEMU migration transport over another channel such as libvirt's secure connection. This is inefficient resulting in many more data copies and lower throughput for migration which reduces chances of it completing.
Providing native TLS encryption support for migration in QEMU will allow for secure migration with a lower performance overhead
