2018-11-26 11:45:50 -0500 | asked a question | North-South router can't connect to external network I'm not able to ping external ip address from inside the network namespace of the router. I'm able to ping the ip address of the router's external interface, 10.204.36.101 from the controller node. Hence, there is a connection between tap-2 and qr. However when i ping the default gateway 10.204.36.1 from inside the network namespace I get destination unreachable response: Command: ip netns exec qrouter.... ping 10 .204.36.1 There are 2 possibilities I can think of:
Here is the output of ip a from inside the router network's namespace: Output from ip -d link list: (more) |
2018-11-26 11:45:50 -0500 | asked a question | How to change the default port for vnc? I am trying to reconfigure the nova-novncproxy server to listen to port 5985 instead of 6080. This is because the openstack nodes are residing on a separate network in front of our corp firewall which only allowed a handful of ports, 5985 being one of them. I reconfigured the [vnc] section in /etc/nova/nova.conf on the compute node as follow: [vnc] Restart the nova services on both controller and compute, restart apache service. I even reboot the whole thing, but doesn't work. nova-novncproxy is still listening on 6080: nothing is listening on 5985: How do I correctly configure vnc to listen to a different port? Thanks so much in advance |
2018-11-26 11:45:47 -0500 | asked a question | how to setup provider network openstack Hi all, I am new to openstack and trying to deploy a 2 nodes openstack queens architecture. The document, I'm following https://docs.openstack.org/install-guide/environment-networking.html (https://docs.openstack.org/install-gu...). My current setup consists of 2 VMs running Ubuntu 16.04 each with 3 NICS ens160, ens192 adn ens224. I configured static IP addresses for ens160 NICs on both VM and this is the management interface The default gateway provides internet access for the VMs to install packages. My /etc/network/interfaces on controller node: Now, I am trying to setup a "provider network" for Openstack so that VM instances within the Openstack Cloud can have internet access. I am using the ens192 NIC to achieve this: My understanding is that, the provider network should be mapped to a different subnet to the management network. Hence, I intend to configure the provider network as followed: Now if I want openstack instances to have internet access I need to configure the default gateway for this provider network which is 10.204.36.1. But the problem is I can only have 1 default gateway configure across all network cards (at least this is what I read). QUESTIONS: 1.Does this mean I need to remove the default gateway from the first NIC ens160? 2.If so will the openstack nodes still have internet access from the "provider network"? Thanks in advance, your time is much appreciated. j Update:So I ended up create the flat provider network through the dashboard. AND then create a Virtual Router connecting 2 openstack private_networks to the provider network. "neutron router-port-list Router" gave output: (more) |
