[Xen-devel] Who gives exeption routine in main.py 'Not found' in ex ?

["Yoshinori Katase" <y_katase@xxxxxxxxxxxxxxxx>]

Hi, Ewan.
I investigated at your suggestion.

When un-existant domain name(id)s is given xm,
exeption routine in main.py is carried 'Not found' in ex.

932:        except xen.xend.XendError.XendError, ex:
933:            if len(args) > 0:
934:                handle_xend_error(argv[1], args, ex)

But in xend.trace, XendEroor shows error DomID.

|      43         if not dom:
|      44             raise XendError('No such domain ' + str(x))
|    |> XendError.py:__init__
|    |  21         self.value = value
|    |< XendError.py:__init__
|    ! Exception:
Traceback (most recent call last):
  File "/usr/lib/python/xen/xend/server/SrvDomainDir.py", line 44, in domain
    raise XendError('No such domain ' + str(x))
XendError: No such domain 100
|    ! Exception:
Traceback (most recent call last):
  File "/usr/lib/python/xen/xend/server/SrvDomainDir.py", line 52, in get
    return self.domain(x)
  File "/usr/lib/python/xen/xend/server/SrvDomainDir.py", line 44, in domain
    raise XendError('No such domain ' + str(x))
XendError: No such domain 100
|    |> XendError.py:__str__
|    |  24         return self.value
|    |< XendError.py:__str__

Who changes xend's error massage ?

Best Regards,
Yoshinori Katase

This is a problem with the exception reporting from Xend (the daemon) to xm
(the client tool).  The exception does not carry enough information to allow
xm to diagnose the problem correctly.  Please feel free to fix this (no-one
else is working on it at the moment).
