Hi All,
I am trying to get the OVS plugin working and am running into strange
problems. The short story is that my guest VMs can not get to the internet
even though the virtual router can. I can also ssh into the guest VMs from
the virtual router. My guest network is 10.10.10.0/24, my Public network
is 10.0.0.0/24 on VLAN 3 (I have a router setup to route the Public network
to internet), and my Management/Storage network is 192.168.2.0/24. All
three represent separate physical networks as well. Any ideas or help
would be greatly appreciated. It seems like it must be a problem with the
virtual router?
Here is some diagnostics I have done:
*********************************
* The router has two interfaces with the same IP address. This seems a
little unusual
