[libvirt] fix spice graphic format issue in function virDomainGraphicsDefFormat

hi, all sub item of spice graphics need to processed like spice channels, that is adding the following lines: if (!children) { virBufferAddLit(buf, ">\n"); children = 1; } the following patch is generated base on git master. ----------------------------------------------------------------------------------------- diff --git a/src/conf/domain_conf.c b/src/conf/domain_conf.c index b30acc8..e42db06 100644 --- a/src/conf/domain_conf.c +++ b/src/conf/domain_conf.c @@ -8127,21 +8127,46 @@ virDomainGraphicsDefFormat(virBufferPtr buf, virDomainGraphicsSpiceChannelNameTypeToString(i), virDomainGraphicsSpiceChannelModeTypeToString(mode)); } - if (def->data.spice.image) + if (def->data.spice.image) { virBufferAsprintf(buf, " <image compression='%s'/>\n", virDomainGraphicsSpiceImageCompressionTypeToString(def->data.spice.image)); - if (def->data.spice.jpeg) + if (!children) { + virBufferAddLit(buf, ">\n"); + children = 1; + } + } + if (def->data.spice.jpeg) { virBufferAsprintf(buf, " <jpeg compression='%s'/>\n", virDomainGraphicsSpiceJpegCompressionTypeToString(def->data.spice.jpeg)); - if (def->data.spice.zlib) + if (!children) { + virBufferAddLit(buf, ">\n"); + children = 1; + } + } + if (def->data.spice.zlib) { virBufferAsprintf(buf, " <zlib compression='%s'/>\n", virDomainGraphicsSpiceZlibCompressionTypeToString(def->data.spice.zlib)); - if (def->data.spice.playback) + if (!children) { + virBufferAddLit(buf, ">\n"); + children = 1; + } + } + if (def->data.spice.playback) { virBufferAsprintf(buf, " <playback compression='%s'/>\n", virDomainGraphicsSpicePlaybackCompressionTypeToString(def->data.spice.playback)); - if (def->data.spice.streaming) + if (!children) { + virBufferAddLit(buf, ">\n"); + children = 1; + } + } + if (def->data.spice.streaming) { virBufferAsprintf(buf, " <streaming mode='%s'/>\n", virDomainGraphicsSpiceStreamingModeTypeToString(def->data.spice.streaming)); + if (!children) { + virBufferAddLit(buf, ">\n"); + children = 1; + } + } } if (children) { -- Coolper Chen
