[libvirt] [PATCH 07/24] src/xenxs: Refactor code parsing Vfb config

introduce function xenParseXMVfb(virConfPtr conf,..........); which parses Vfb config instead signed-off-by: Kiarie Kahurani <davidkiarie4(a)gmail.com&gt; Signed-off-by: Kiarie Kahurani <davidkiarie4(a)gmail.com&gt; --- src/xenxs/xen_xm.c | 301 +++++++++++++++++++++++++++-------------------------- 1 file changed, 155 insertions(+), 146 deletions(-) diff --git a/src/xenxs/xen_xm.c b/src/xenxs/xen_xm.c index f4bb37d..228e0a2 100644 --- a/src/xenxs/xen_xm.c +++ b/src/xenxs/xen_xm.c @@ -40,6 +40,7 @@ #include "virstoragefile.h" #include "virstring.h" +#define MAX_VFB 1024 /* Convenience method to grab a int from the config file object */ static int xenXMConfigGetBool(virConfPtr conf, const char *name, int *value, int def) @@ -689,7 +690,158 @@ xenParseXMDisk(virConfPtr conf, virDomainDefPtr def, return 0; } -#define MAX_VFB 1024 + + +static int +xenParseXMVfb(virConfPtr conf, virDomainDefPtr def, + int xendConfigVersion) +{ + int val; + char *listenAddr = NULL; + int hvm = STREQ(def->os.type, "hvm"); + virConfValuePtr list; + virDomainGraphicsDefPtr graphics = NULL; + + if (hvm || xendConfigVersion < XEND_CONFIG_VERSION_3_0_4) { + if (xenXMConfigGetBool(conf, "vnc", &val, 0) < 0) + goto cleanup; + if (val) { + if (VIR_ALLOC(graphics) < 0) + goto cleanup; + graphics->type = VIR_DOMAIN_GRAPHICS_TYPE_VNC; + if (xenXMConfigGetBool(conf, "vncunused", &val, 1) < 0) + goto cleanup; + graphics->data.vnc.autoport = val ?
