[Qemu-devel] [PATCH 10/11] Error out when tls-channel option is used wit


From: Gerd Hoffmann
Subject: [Qemu-devel] [PATCH 10/11] Error out when tls-channel option is used without TLS
Date: Tue, 28 Feb 2012 17:30:01 +0100

From: Christophe Fergeau <address@hidden>

It's currently possible to setup spice channels using TLS when
no TLS port has been specified (ie TLS is disabled). This cannot
work, so better to error out in such a situation.
