So, the file /var/lib/xenstored/tdb was corrupted... and launching xenstored with the
"no-recovery" option did not help.
I dropped the file and that works fine now...
But I don't understand why this file is keeped "as is" on dom0 reboot...

Le 17/08/2010 19:42, Olivier B. a écrit :
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.

How can I debug that ?
