Xen users - Aug 2006 - Fw:Xend start and after lose network

Objet  : Xend start and after lose network

Hi everybody :

My configuration :
Dapper 6.06 LTS with all updates
Xen 3.0.2.2

My problem :
After making ''xend start'', I lose network connections between
my server and local network or internet.
Nota : domU cas normally access to network

I read about a similar problem in the bugtracker (N. 62) but
it seems that this is normally corrected in xen 3.0.2.2. I
read some messages about similar problems but found no solution.

Some help would be really appreciated
Thanks a lot
