[libvirt] [PATCH] fix some error report when on remote access

When querying about a domain from 0.3.3 (or RHEL 5.3) domain located on a 0.6.3 (RHEL-5) machine, the errors are not properly reported. This patch from Olivier Fourdan <ofourdan@redhat.com> , slightly modified to not change the semantic when the domain os details cannot be provided is attached, thanks !
