[Xen-users] vif = [ ''ip=172.48.0.101'' ] error on "xm reboot"

Hi,

i got the following error message in /var/log/xend.log when i try to 
reboot a running domU with "xm reboot".

Creating a new domU with the same domU.sxp works like expected, the
error occurs only on reboot.

Is this a bug or expected behaviour?

Re: [Xen-users] vif = [ ''ip=172.48.0.101'' ] error on "xm reboot"

This is the answer I got when asking the same question  to the list just 
a couple of days ago :

This was a problem with the xend code to store the vif''s ip
information.
Use xen-unstable (which I''d currently reccoment, it''s getting
closer
to 3.0.2 every day  ;)  or just change the

  if ip:
            result.append( ...

code in
/usr/lib/python/xen/xend/server/netif.py (or your sourcetree)
to:
       if ip:
            for i in ip.split(" "):
                result.append([''ip'', i])
(thats how unstable does it) or to:
       if ip:
            result.append([''ip'', ip])
(thats an older fix which doesn''t handle multiple IPs)

on DomU reboot  :)
