Hi,

I can't start xend anymore and wanted to ask if anyone had similar problems in the past. Also every suggestion to solve that issue is very welcome - actually I hope someone has a hint for me ;-)

It used to work before with some older source tree for xen & linux. I tested my old xen/dom0 image that used to work together with the new tools but that throws the same errors (I need to go to the new version anyway so stepping back would be only a bug trackiong option anyway). I already moved to the current head of xen-unstable.hg and linux-ppc-2,6.hg and recompiled everything. I used to build/boot debug images but the error occurs also with non debug images.

Here I post the information what I got out of my logs on my system so far. Important facts are:

- exception "metrics" ???
- there is some phyton/xen rocess listening on port 8002
