ip aliases on a routed network
When using a routed netword xen setup ( network-route ), every domU needs an entry in the routing table to be accessible.
So, in addition to configuring the ip on the domU, you also need to tell xen which ip’s you want to use.
In the domU config file:
vif = [ 'ip=10.0.0.1 10.0.0.2 10.0.0.3']
Will route 10.0.0.1 10.0.0.2 and 10.0.0.3 to this domU
