[Xen-users] intermittent domU network problems

[JimBow <jimbow@xxxxxxxxx>]

Hi all,

have a strange and recurring network problem with a domU host. 
Setup: Debian etch is running in domU on Debian etch dom0, xen 3.0.2
The xen network is configured in a bridged mode and there are no 
firewalls on any of xen domains.
Every now and again the domU host losses its connection to the 
Ethernet network. By loses I mean all network connectivity ceases - 
from arp to anything else I pass down the NIC. This leaves the host 
effectively useless as a server.
This event does not leave any traces in the logs on the domU or dom0 
hosts and happens at seemingly irregular intervals. SNMP graphs dont 
show anything unusual either.
Running the Debian network init script doesn't fix the problem, the 
only way to fix it is by restarting the domU host.
Im not sure if this is even a xen issue, but perhaps someone here 
can recognise this or have anything to suggest?
Thanks for reading and any tips.


JimBow
