RE: [Xen-users] 3.0.2 NAT headaches
Hi John,
Have you applied the fix for the potential packed header corruption on Xen
DomU interfaces?
root@harpseal:~# cat /etc/network/if-up.d/fix-xen
#!/bin/bash
if [ $IFACE != "lo" ] ; then
ethtool -K $IFACE tx off
fi
root@harpseal:~#
I have to have this script on all my DomUs to make the networking reliable.
