on the hosts:
uname -a
Linux XXXX 2.6.31-16-server #53-Ubuntu SMP Tue Dec 8 05:08:02 UTC 2009
x86_64 GNU/Linux
I been told that today the network when down again and one of the guys
here had to log using the console and restart it for that particular
guests..
on the guest:
uname -a
Linux XXXX 2.6.27.25-170.2.72.fc10.x86_64 #1 SMP Sun Jun 21 18:39:34 EDT
2009 x86_64 x86_64 x86_64 GNU/Linux
Next time it goes down I will try to run a sniffer and try both sides.
