I'm guessing CentOS 6.2.

The error is right there in the output:

  qemu-kvm: -drive
  file=/VM/Ubuntu-Media/Ubuntu-Media-Copy.vdi,snapshot=on,if=virtio: could not
  open disk image /VM/Ubuntu-Media/Ubuntu-Media-Copy.vdi: Operation not supported

qemu cannot understand this file.  It could well be that VDI support
is disabled in CentOS, or the file format is some later variant that
qemu doesn't support.

There's a newer version of libguestfs in RHEL 6.3, but the basic
problem here is with qemu.
