More Xen troubles (with xend this time)

["Jérôme Petazzoni" <jp@enix.org>]

When trying to reproduce a crash (when I do "xm restore foo.xen", the 
restored VM crashed instantaneously), I hit the following "bug" (I hope 
that the problem lies between my keyboard and my chair and that I didn't 
find another real bug) :

I did restore the domain, then noticed it was crashed ("-----c" in xm 
list). I tried to destroy it, but it didn't work. So I stopped xend, 
restarted it ... And there it goes :

isnpro:~# xm list
(111, 'Connection refused')
Error: Error connecting to xend, is xend running?

isnpro:~# xend start

isnpro:~# xm list
(111, 'Connection refused')
Error: Error connecting to xend, is xend running?

(many "Xend Daemon started" messages since I tried many times to restart 
it...)

So I thought that xfrd (xend?) was running on port 8002 instead of 8000, 
and I tried to setup a redir (who knows!) :

isnpro:~# redir --cport 8002 --lport 8000  &
[1] 14025
isnpro:~# xm list
Traceback (most recent call last):
  File "/usr/sbin/xm", line 9, in ?
    main.main(sys.argv)
  File 
"/root/Xen/xen-2.0-testing.bk/dist/install/lib/python/xen/xm/main.py", 
line 795, in main
  File

  File 
"/root/Xen/xen-2.0-testing.bk/dist/install/lib/python/xen/xm/main.py", 
line 343, in main
AttributeError: 'str' object has no attribute 'sort'

Okay, it seems it wasn't a very clever idea after all.

What should I try now ? (I don't want to reboot the thing yet, since the 
virtual domains are still running and I can't stop them right now).
