If you can't run crash on the live system, then you can't run it
on a crash dump.  

For both the live system, and the dumpfile, you need either:
  
  (1) the original debuginfo-full vmlinux file for kernel 2.6.32.12-0.7-xen, or
      if that doesn't exist,
  (2) a rebuilt 2.6.32.12-0.7-xen debuginfo-full vmlinux kernel along with the
      *original* 2.6.32.12-0.7-xen System.map file

Then you should be able to run on both the live system and with the dumpfile:

  $ crash vmlinux System.map   
  $ crash vmlinux System.map dumpfile
