Can you try a fresh build with this applied and see if that helps.
I have applied this patch. I think libfsimage is somehow not being
affected with this. Yet, linking /usr/lib64/fs ->  /usr/lib/fs solves
the problem.
libfsimage is going to blindly look in /usr/lib64 on non-Itanium
64-bit Linux platforms. See tools/libfsimage/common/fsimage_plugin.c:134
Oh bloody hell, I hadn't spotted that.

We should definitely be setting FSIMAGE_FSDIR to something sane based on
LIBDIR and not letting all sorts of weird heuristics kick in.


#if defined(FSIMAGE_FSDIR)
         if (fsdir == NULL)
                 fsdir = FSIMAGE_FSDIR;
#elif defined(__sun__)
         if (fsdir == NULL)
                 fsdir = "/usr/lib/fs";

         if (sizeof(void *) == 8)
                 isadir = "64/";
#elif defined(__ia64__)
         if (fsdir == NULL)
                 fsdir = "/usr/lib/fs";
         if (fsdir == NULL) {
                 if (sizeof(void *) == 8)
                         fsdir = "/usr/lib64/fs";
                         fsdir = "/usr/lib/fs";


SOOO, just wondering, in the above patch, should these:

-LIBLEAFDIR_x86_64 ?= lib64
+LIBLEAFDIR_x86_64 ?= lib

be also changed if installing the latest Xen 4.2-unstable on like Debian Wheezy? OR is this something that is not important that important?

Just curious since even in the latest Xen 4.2-unstable rev-25494, it still has the

LIBLEAFDIR_x86_32 = lib
LIBLEAFDIR_x86_64 ?= lib64

in the StdGNU.mk file.
