Hi, Virsh domname <uuid> command for shut-off domain fails on xen-3.0.4. I think that xm_internal.c shoud be modified. But, it seems that xm_internal's structure isn't for xen-3.0.4, and shut-off domain's information is got from xend. I make a patch for xend_internal.c The attached patch resolve this issue in the following way: 1) If the domain's name can't be pulled out from the running domains list by uuid, request xend by "/xend/domains/<uuid>". 2) If the domain's data can be teken from xend, pull out the domain's name.
