Hi,
Im using Xen testing from 14 Aug 2005.
I have 3 DomU machines.
Everything works most of the time, but occasionally (about once a
week), and not assocaited with any heavy usage, the network dies.
I can still ssh into the Dom0 machine, but that cannot see any of my
DomU machines.
I can connect via console to the DomU machines, and they cannot see
'out' either. They are however running fine (albeit without
networking)
Any ideas how to start debugging this? has anything like this been
fixed in testing since 14 aug?
When its not wokring, I tried ifconfig and brctl, and to my untrained
eye it all looks fine.
How can I find out whats not working???
thanks

(When its working, IFConfig gives
