Re: [libvirt] [PATCH v2 12/12] 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 <listen type='none'/>. In order to be able to migrate to old libvirt the migratable XML will be generated without the listen element and with autoport='no'.

+ /* If spice graphics is configured without ports and with autoport='no' then + * we start qemu with Spice to not listen anywhere. Let's convert this + * configuration to the new listen type='none' which does the same. */ + if (def->type == VIR_DOMAIN_GRAPHICS_TYPE_SPICE) { + glisten = &def->listens[0]; + + if (glisten->type == VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_ADDRESS && + glisten->port == 0 && glisten->tlsPort == 0 && !glisten->autoport) { + VIR_FREE(glisten->address); + glisten->type = VIR_DOMAIN_GRAPHICS_LISTEN_TYPE_NONE; + } + } +
