When QEMU gains TLS support, however, there will need to be a TLS negotiation done inbetween creation of the QIOChannel and creation of the final QEMUFile. Introduce some helper methods that will encapsulate this logic, isolating the migration protocol drivers from knowledge about TLS. Reviewed-by: Dr. David Alan Gilbert Signed-off-by: Daniel P.
