From 69ef1f36b0f882fc5ba9491fb272fa5f83ac1d3d Mon Sep 17 00:00:00 2001 From: "Daniel P. Berrange" Date: Wed, 27 Apr 2016 11:05:15 +0100 Subject: migration: define 'tls-creds' and 'tls-hostname' migration parameters Define two new migration parameters to be used with TLS encryption. The 'tls-creds' parameter provides the ID of an instance of the 'tls-creds' object type, or rather a subclass such as 'tls-creds-x509'. Providing these credentials will enable use of TLS on the migration data stream. If using x509 certificates, together with a migration URI that does not include a hostname, the 'tls-hostname' parameter provides the hostname to use when verifying the server's x509 certificate. This allows TLS to be used in combination with fd: and exec: protocols where a TCP connection is established by a 3rd party outside of QEMU. NB, this requires changing the migrate_set_parameter method in the HMP to accept a 's' (string) value instead of 'i' (integer). This is backwards compatible, because the parsing of strings allows the quotes to be optional, thus any integer is also a valid string. Reviewed-by: Dr. David Alan Gilbert Signed-off-by: Daniel P.
