Re: [Xen-devel] Migration Errors

[Arthur Bergman <abergman@xxxxxxxxxxx>]

Hi,

This is most likely the same problem as I have, you will find that xm  
save doesn't work either.
http://article.gmane.org/gmane.comp.emulators.xen.devel/5859/ 
match=arthur+bergman
is the thread that I describe this, I am stuck now because I don't know  
how to get the required debugging information.
the segfault is inside libxc called from xfrd

Cheers
