Re: [Xen-users] Slow network speed with Xen 3.2-1
I had a similar problem and the solution was to disable checksum
offloading in the domU.
sh# ethtool -K eth0 tx off
You can add this to your /etc/network/interfaces, too..
post-up ethtool -K eth0 tx off
I also had to disable this in my dom0 for dhcp to work...
