[Libvirt-cim] [PATCH V3 08/11] device parsing, add debug print

[Wenchao Xia]

  Sometime libvirt will fail in these API when there are low level error,
what we saw is libvirt can't got xml for some domain. This patch add
debug log when met this error, so in future we can know where is wrong
better.

v2:
  Rebased.
