Description Dave Ludlow 2006-04-08 10:08:26 EDT

Description of problem:
The xen-3.0.1-cloexec.patch introduces a regression that breaks the "xm save"
command - or more specifically, the xc_save program that it calls.

The discussion at the URL listed sums it up.  Either the cloexec patch needs to
be removed or the close-on-exec flag needs to be cleared in XendCheckpoint.py.

Version-Release number of selected component (if applicable):
3.0.1-4

How reproducible:
Every time

Steps to Reproduce:
1.Execute "xm save domain filename" on a running domain
  
Actual results:
An error is returned and the following goes into xend.log:
Unable to get platform info.: 9 at XendCheckpoint:227

Expected results:
The domain's state and config should be saved to the file.

Additional info:
The migrate command is also broken as a dependency.
I'm not related to the mailing list thread in the URL, it's something I found
while troubleshooting.  I have confirmed that applying the attached patch and
rebuilding the RPM fixes the bug.

Comment 2 Rik van Riel 2006-04-10 11:56:08 EDT

Thanks for the patch.  Daniel, want to add this to our RPM?

Comment 3 JM 2006-04-17 09:19:44 EDT

"xm migrate" calls "xm save" and so "xm migrate" fails too.

Comment 4 Daniel Veillard 2006-04-18 13:06:53 EDT

Okay, reproduced and confirmed the fix, I'm pushing xen-3.0.1-5 to rawhide
and xen-3.0.1-5.FC5 to FC5 testing later.
For migrate it's a different problem !

  thanks !

Daniel

xen-3.0.1-5.FC5 has been released for a long time now, fixed there.
W.r.t. migration the last time I tried one month ago this worked just fine,
with a pre 3.0.3 release.
