Lutz, does xen-unstable actually work for you after this change is applied? xm start <guest> fails for me on SLES11, as first reported here: http://lists.xensource.com/archives/html/xen-devel/2010-08/msg01461.html My python skills are not good enough to fix it, and this change looks like the only one between rev 21976:22019 that touches self.getWeight() related code in XendDomainInfo.py [2010-08-27 14:36:38 4654] ERROR (XendDomainInfo:488) VM start failed Traceback (most recent call last): File "/usr/lib64/python2.6/site-packages/xen/xend/XendDomainInfo.py", line 473, in start XendTask.log_progress(0, 30, self._constructDomain) File "/usr/lib64/python2.6/site-packages/xen/xend/XendTask.py", line 209, in log_progress retval = func(*args, **kwds) File "/usr/lib64/python2.6/site-packages/xen/xend/XendDomainInfo.py", line 2618, in _constructDomain assert type(weight) == int AssertionError Olaf _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
