Hi,
My bridging stops when I start a third Xen domain !?!?
I have a few domains setup (mail, wiki, pbx). If I start two domains
bridge networking works great. But if I start a third, either the new
domains does not work or one of the other DomUs stops working! By
stop working I mean I can't route traffic outside of Dom0. I have
been looking at this on and off for a couple of weeks. Any insight or
things I should look at would be greatly appreciated.
I don't want to bombard this email with 10,000 dumps. I will gladly
post any information needed to figure this one out.
Basic network is a 10.20.10.X network.
Gateway is 10.20.10.1
Xen Dom0 IP is 10.20.10.125
Xen Mail domain is 10.20.10.150
Xen PBX domain is 10.20.10.152
Xen wiki domain is 10.20.10.153
