Re: [Xen-users] Fixed MAC address causes spurios network connectivity lo
I think I'm also having the same problem.
I have been running 3 domU's all day and everything worked fine.
Just now all but dom0 stopped responding to all network activity.
I've shutdown all domU and restarted them one at a time, but they still
are not reachable.
Is this a config problem or a bug?
I am running Xen 3.0 installed from the FC4 xen install script.

the same machine, all of them with assigned fixed MAC addresses
(all unique). Occasionally one of the domU's losses its network access (there is very little network activity). I cannot ping it from the outside in dom0 or from the other domUs. No error messages from
XEN or Linux. Sometimes it works, sometimes it doesn't. I did a network
trace of the ping and it looks as if the ARP response is not getting
back to the domU (when pinging from within domU). If I manually
update the ARP table in the domU myself, the ping starts working.
Also, if I set the ageing on the bridge to be 0, this also fixes the
problem (but a bad workaround). I am using XEN 2.07 on an AMD opteron. Has anyone resolved this problem?
Thanks, Eric
