Thanks for your reply. I discoverd my problem as I posted to this mailinglist
earlier.

I discovered to problem!
I don't know why - but the trouble started from the time after I set the ip-
adress for the dom0 to one ip from the same network as the guests. Until
yesterday I had a private IP 172.16.0.1 for my dom0 where all other Computers
in the LAN had public IPs. But to have better access to the dom0 I decided to
change this to one IP from the same public network - and this was the
problem.
After I switched back to the private IP all is working fine again. network is
stable since hours now
I don't know what the problem is in this case. Maybe something with arp?
