Unfortunately strace doesn't give the sort of information needed to
diagnose this. Can you run the daemon under gdb? When it crashes you can
type "bt" to get a backtrace. If there are debuginfo packages available
in your distro installing the ones for the Xen packages would improve
the output of this too.


i don't really know how to enable the debugging info for these libraries. I can't see anything on Google about debuginfo packages for Ubuntu 12.04. Incidentally i just grabbed the xen version in there repo following this : 

https://help.ubuntu.com/community/Xen

i did grab a copy of the source of xen 4.1.2 and compiled it with debug in the tools, so that is why i can see proper output for the first two
