This dependency is required for adequate Parallels images support. Typically the disk consists of several images which are glued by XML disk descriptor. Also XML hides inside several important parameters which are not available in the image header. The patch also adds clause to checkpatch.pl to understand libxml2 types. In the other case there is the following false positive: ERROR: need consistent spacing around '*' (ctx:WxB) #210: FILE: block/parallels.c:232: + !xmlStrcmp(root->name, (const xmlChar *)"Parallels_disk_image")) Signed-off-by: Denis V.
