Xen users - Nov 2008 - xm save fails

Hi,

I want to save a domain, but get:

-----8<---
xm save drbdtest-linux /tmp/1
Error: /usr/lib64/xen/bin/xc_save 26 91 0 0 0 failed
-----8<---

In xend''s log, this has been logged:
-----8<---
[2008-11-08 18:26:01 32399] INFO (XendCheckpoint:373) All memory is saved
[2008-11-08 18:26:02 32399] ERROR (XendCheckpoint:144) Save failed on domain
drbdtest-linux (91).
Traceback (most recent call last):
  File
"/usr/lib64/python2.5/site-packages/xen/xend/XendCheckpoint.py", line
112, in save
    forkHelper(cmd, fd, saveInputHandler, False)
  File
"/usr/lib64/python2.5/site-packages/xen/xend/XendCheckpoint.py", line
361, in forkHelper
    raise XendError("%s failed" % string.join(cmd))
XendError: /usr/lib64/xen/bin/xc_save 26 91 0 0 0 failed
-----8<---

System is an opensuse 11 - maybe their XendCheckpoint.py is somewhat
broken? I am not a python guru, sadly.
Any help is appreciated,

Rainer

Just to be sure: You mean xc_domain_save, not xc_save, correct?
(http://lxr.xensource.com/lxr/source/tools/libxc/xc_domain_save.c?a=x86_64#L749)

That is true, in fact, the domain gets saved and can be restored. That
is the good part. The bad part to me is: I need xm migrate, which
somehow uses the same code :-(
