Use tcpdump and/or Wireshark on your network bridge and look at the
packet output.

Hi list! 

I have a couple of Tyan transport servers with a mix of CentOS 5.4,
CentOS 5.3 and Ubuntu server 9.10 as DomUs. 

The Dom0 is CentOS 5.4 on both boxes. Networking is xen bridged with a
mix of public and private IPs for the DomUs which works as intended most
of the time. 

Everything works fine, but suddenly some of my virtual machines at
random intervals lose connectivity, mainly the Ubuntus that work as
internal and external DNS. Sometimes I need to restart networking on the
machines, sometimes I need to reboot the DomUs to regain connectivity. 

Instead of pasting lots of config files, could you point me in the right
direction where can I start debugging? 

Thanks, 
Rubén
