Description Daniel Berrangé 2016-01-22 11:12:25 UTC 
Description of problem:
The default QEMU migration transport runs a clear text TCP connection between the two QEMU servers. It is possible to tunnel the migration connection over libvirtd's secure connection but this imposes a significant performance penalty. It is also not possible to tunnel the NBD connection use for block migration at all.

As a step towards securing the management network we need to have Nova configure QEMU to use native TLS support on its migration and NBD data transports, without any tunnelling.
Comment 4 Kashyap Chamarthy 2018-04-05 16:45:20 UTC 
This depends on the libvirt support for TLS encryption for NBD disks.  Refer the following libvirt RFE bug in-progress:

native TLS encryption for NBD disk access
