I have setup a machine with xen, these days. But got a problem now. I setup a dom0 with ip address 192.168.1.210/255.255.255.0, vm1 with ip addr 192.168.1.101/255.255.255.0, and vm2 with ip addr 192.168.1.102/255.255.255.0. All with default gateway 192.168.1.1. Now the problem is vm1 and vm2 can not ping each other, but they can ping dom0 and other machines within the subnet. any one can help me with this problem? thank you very much. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

I worked around the problem by running the following command on the dom0 machine. ethtool - K eth0 tx off I am under the impression that the problem has been fixed in the next version. Hope this helps. Cheers, Brad _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Finally, I found the problem is caused by misconfig of the shorewall firewall! John, Thank you for your help. And Brad, thank you for your help too. Best regards.
