Hi,

After I live migrate a VM from one Xen host to another, the networking on the VM stops until I do something like arping it from a server on the same network, or login to the console of the VM and use the network in some way (eg. ping another server, start tcpdump, check a host name).

I have configured the networking as per: http://sourceware.org/cluster/faq.html#xenclustererrors because of fencing issues. Everything works perfectly, except that until something happens with the networking on the VM, the networking is stopped.

Any thoughts? I'm not sure what information to send--this is Redhat EL5.1.

Thanks,
MO.THER>
