[Xen-users] xend does not start

["Olivier B." <xen.list@xxxxxxxxx>]

 Hi,

I have a Xen server which doesn't work anymore (xend refuse to start), 
apparently without any modification in configuration.
Since it was an "old" Debian testing with Xen 3.4, I upgrade to the last 
debian testing packages, with Xen 4.0.
But I obtain the same problem : xend does not start.
I verified that Xen is running (with a pvops kernel from Debian, or 
2.6.32.16 and 2.6.32.19 from Jeremy's Git), and xenfs (/proc/xen) is 
mounted.
In logs I have this errors :
[2010-08-17 19:04:16 2339] INFO (SrvDaemon:220) Xend exited with status 1.
[2010-08-17 19:07:57 5348] INFO (SrvDaemon:332) Xend Daemon started

How can I debug that ?

Thanks,
