[PATCH] patch for virsh domname <uuid> command error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
