2015-01-22 04:38:40 -0500 asked a question Floating IPs on Hetzner

Hello, I have a problem with my OpenStack on Hetzner servers. Seems like hetzner provides isolated IPs or subnet parts, not hole subnets, also every IP or block of IPs are attached on the MAC of the physical server. So I can't assign a floating IP on a VM because the IP is bind to the physical server'w MAC.

Does anyone found a solution on this?

Thanks, Alex

2014-10-30 10:34:03 -0500 commented answer Instances are accessible only from network node

http://justpaste.it/hrwa These are the neutron/nova confs for all three nodes. You didn't tell me what "external" represents above.

2014-10-30 09:55:44 -0500 commented answer Instances are accessible only from network node

Yes, didn't work either. Would you have a look at my neutron.conf on network node? http://justpaste.it/hrvt At "flat_networks = external" and "bridge_mappings = external:br-ex" external is the name of my external network of is a default value.

2014-10-30 09:04:55 -0500 commented answer Instances are accessible only from network node

I deleted this route and I can ping 4.2.2.2, but I still can't ping the gateway of the neutron router from anywhere except from network node and the instances. Also from the instance I can ping the br-ex IP but not the management IP of network node.

2014-10-30 08:48:42 -0500 commented answer Instances are accessible only from network node

Didn't work. This is odd. Maybe is a packet forwarding or firewall thing because I can ping the br-ex interface from the instance and the other nodes. Also I can ping the instance from network node.

2014-10-30 08:37:50 -0500 commented answer Instances are accessible only from network node

The networks 192.168.10.0 192.168.20.0 192.168.30.0 have ther gateways(192.168.10.l254, 192.168.20.254, 192.168.30.254) on a pfsense router, and no I don't have DNS server if that is what you mean. http://justpaste.it/hrun

2014-10-30 08:26:49 -0500 commented answer Instances are accessible only from network node

neutron subnet-create demo-net --name demo-subnet --gateway 10.0.0.1 10.0.0.0/24 and yes I lauch it on internal. These are my interfaces http://justpaste.it/hruk

2014-10-30 08:14:46 -0500 commented answer Instances are accessible only from network node

I use as external net 192.168.30.0/24. "neutron subnet-create ext-net --name ext-subnet --allocation-pool start=192.168.30.100,end=192.168.30.200 --disable-dhcp --gateway 192.168.30.254 192.168.30.0/24" 192.168.30.254 is the IP of the physical router, and 192.168.30.1 is br-ex IP. Is that correct?

What do you mean by add the DNS to br-ex and to the external,internal net? I followed the official centos guide. Also tell me something, the neutron router gateway is the br-ex IP?

2014-10-29 10:35:12 -0500 asked a question Instances are accessible only from network node

Hello I have a three node installation (controller, network, compute), I've set up everything except external networking. I can access instances from network node (both on private IP and Floating IP), but I can't access them from anywhere else and instances cannot access external network (only network node's br-ex IP, neutron router public gateway and other instances). Does anyone know how to fix this? Thanks in advance Alex

2014-09-30 07:38:34 -0500 asked a question General questions about Neutron

Hello, I am trying to install OpenStack and I am really stuck on Neutron (I am following the official guide). I have one controller, 1 Network and 1 compute node. All three of them running CentOS.

I have two general questions:

  1. For bridging: The commands "ovs-vsctl add-br br-int" and "ovs-vsctl add-br br-ex" take care of bridging or I have to create the files too? (by files I mean "/etc/sysconfig/network-scripts/ifcfg-br-int and .../ifcfg-br-ex")
  2. I don't have a public subnet so I want to test OpenStack only with private subnets. How can I accomplish that?

2014-08-26 08:44:52 -0500 commented answer neutron configuration without public network

I am not using packstack, but the openstack guide for centos. Just a question: the configuration for br-ex I do in manually by adding the /etc/sysconfig/network-scripts/ifcfg-br-ex file? Or openstack does that job when I type ovs-vsctl add-port br-ex eth1?

2014-08-26 04:26:56 -0500 asked a question neutron configuration without public network

Hello, I am trying to install openstack on two nodes. controller-compute. They are running centos. I am on the testing part, so I don't have a public subnet. I am trying to make it work only with private IPs. Is it possible? Also, I have only 2 interfaces on both of them and I don't know how to configure the .../network-scripts/ifcfg-eth* Any suggestions?

2014-07-24 14:17:34 -0500 commented answer Instance incoming connection doesn't work

I solved my problem. It seems that I had to assign a floating IP to the instance in order to access it from outside its compute node. Thank you dbaxps for your time and your help. Much appreciated.

2014-07-23 07:38:55 -0500 commented answer Instance incoming connection doesn't work

I haven't set a floating IP network yet. I am trying to ensure connectivity locally. Here is my configuration:

controller: one interface(eth0) on management network.(192.168.1.35)

compute nodes: one interface(eth0) on management network(192.168.1.45), and one interface(eth1) on instance network

the eth1 interface is on br100. The fixed range for my VMs is 192.168.1.96/29.

I also have one more question. With this configuration what must be the value of public_interface in nova.conf

public_interface=eth0 or public_interface=eth1 ?
