Sorry, i have asked for a stupid bug. Let us check following one.

[...]
114 static int
115 virStorageBackendSheepdogRefreshPool(virConnectPtr conn ATTRIBUTE_UNUSED,
116                                      virStoragePoolObjPtr pool)
117 {
118     int ret;
119     char *output = NULL;
120     virCommandPtr cmd;
121
122     cmd = virCommandNewArgList(COLLIE, "node", "info", "-r", NULL);
123     virStorageBackendSheepdogAddHostArg(cmd, pool);
[...]

virCommandNewArgList may return ‘NULL’, so i think we should check
this condition, which we need not do following stuffs, right?
