rpath maybe?  You can try debugging this using the following commands:

  printenv | grep LD_
  which virt-sysprep
  ldd `which virt-sysprep`
  eu-readelf -d `which virt-sysprep`
  chrpath `which virt-sysprep`

virt-top is 'top' for virtual machines.  Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.
