Hi Havent,

Based on your environment details, you two shared networks:

1) 10.10.10.0/24 -> gateway @ 10.10.10.1 2) 8.8.8.0/24 ->gateway @ 8.8.8.1

Since you have created both of these networks as "shared"/public networks, any VM on any network can ping the gateways, which is what you are seeing.

Second, the VMs on 10.10.10.0/24 network, dont seem to have an IP on 8.8.8.0/24 network based on your 'nova list' output. This can be due to incompatibility with your guest image or the way you are spinning up the VMs the command or API call to launch the VM. It would be helpful if you can provide that command or API call as well.

I also noticed that you were using FlatDHCPManager before QuantumManager, in order to migrate from FlatDHCPManager to QuantumManager, you are required to delete all network and VMs created using FlatDHCPManager before re-launching nova-network with QuantumManager.

Another question for you, are you using Nova DHCP or Fixed IP for IP assignment?

Thanks,

s0mik

ping 8.8.8.2

But,

I wonder how this situation happened? Thanks.
