RE: [Xen-devel] Unexpected error: httplib.BadStatusLine on create tests

["Petersson, Mats" <mats.petersson@xxxxxxx>]

In my experience, httplib.BadStatusLine is a result of xend dying,
rather than the other way around... 

It's possible to (sort of) debug xend by attaching a GDB to the process
running xend - start xend as usual, "ps ax|grep xend", and pick out the
process number for xend, then start gdb and do "attach X" where X is the
process ID of the xend process ["python xend start" or similar]. At
least you may have a chance of seeing why xend dies.
