Berrange\" <berrange@redhat.com>\n\nHistorically the migration data channel has only needed to be\nunidirectional. Thus the 'exec:' protocol was requesting an\nI/O channel with O_RDONLY on incoming side, and O_WRONLY on\nthe outgoing side.\n\nThis is fine for classic migration, but if you then try to run\nTLS over it, this fails because the TLS handshake requires a\nbi-directional channel.\n\nSigned-off-by: Daniel P.
