From c34ada0996e4c2dcfa3e0f40db633ecb34405f9e Mon Sep 17 00:00:00 2001 From: Pavel Hrdina Date: Wed, 18 May 2016 08:33:28 +0200 Subject: [PATCH] spice: introduce listen type none This new listen type is currently supported only by spice graphics. It's introduced to make it easier and clearer specify to not listen anywhere in order to start a guest with OpenGL support. The old way to do this was set spice graphics autoport='no' and don't specify any ports. The new way is to use . In order to be able to migrate to old libvirt the migratable XML will be generated without the listen element and with autoport='no'. Also the old configuration will be automatically converted to the this listen type.

none since 1.3.6 (QEMU only)
+
+

+ This listen type doesn't have any other attribute. Libvirt supports + passing a file descriptor through our APIs virDomainOpenGraphics() and + virDomainOpenGraphicsFD(). No other listen types are allowed if this + one is used and the graphics device doesn't listen anywhere. You need + to use one of the two APIs to pass a FD to QEMU in order to connect to + this graphics device. Supported by graphics type spice. +
