Open Stack

Take a look at the limitations section of the Quantum docs. You will need to set allow overlapping IP's to false and make sure you have bidirectional network connectivity between the metadata ip and the tenant private network(s).  The L3 agent.ini also should be configured with the metadata ip.  The docs cover these topics in more detail.

Hi!

 My Quantum Single Flat is almost working!

 My Instance get an IPv4 without any problem but, the metadata isn't working...

 What can I do?

 My compute node have the `nova-api-metadata' package, nova.conf have `metadata_host = 10.32.14.234', the iptables `169.254.169.254' NAT rule is there too...

 The Instance log shows:

Guys,

 Here: http://docs.openstack.org/trunk/openstack-network/admin/content/demo_flat_installions.html

 ...at the step "1. Install the L2 agent." but, what is the name of the Ubuntu package (I'm using Folsom)?

 ...apt-get install what?

quantum-plugin-openvswitch-agent


 I thought that the Quantum L2 agent was the package `quantum-plugin-linuxbridge' but, this doc uses OpenvSwitch... So, I'm confused now...

As you know Quantum uses plugins to realize the network abstractions. Some plugins (such as OVS) use an agent to collect information from the Quantum db to implement the logical data model on the local vswitch.


 The following packages "quantum-server quantum-plugin-openvswitch quantum-plugin-openvswitch-agent quantum-dhcp-agent" will be enough for my `controller+network node'?
That should work for flat networking implementations.


 At the compute-node, I'll install only the "quantum-plugin-openvswitch-agent", right?
Correct. That package should install the openvswitch and other dependencies.


Tks,
Thiago

Daneyon,

 Thank you for your time! I'll check it!

 I read that guide from Cisto once... Too complex.

 I also, tried the following guides too, appears to be like the one from Cisco:

 https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/stable/GRE/OpenStack_Folsom_Install_Guide_WebVersion.rst

 and:
 https://github.com/mseknibilel/OpenStack-Folsom-Install-guide/blob/GRE/2NICs/OpenStack_Folsom_Install_Guide_WebVersion.rst


 Anyway, at first, I do not want L3 or GRE. Only the most basic setup (Flat / L2).

 Do you know if my `controller+network node' server eth0 needs to be promisc?

Tks!
Thiago

Make sure the quantum-dhcp and l3 agents are running and properly configured.  It sounds like either the q-dhcp agent is not functioning or connectivity between the dhcp agent and vm is not functioning.  If using GRE tunnels, test connectivity between the tunnel endpoints.  You should also see the IP's of your tunnel peers in ovs-vsctl show.  If your instance spawns successfully, console into it and manually assign an IP and ping the q-l3-agent and q-dhcp agent.  You can follow this guide for deploying Quantum with OpenvSwitch using GRE tunnels:

Subject: Re: [Openstack-operators] Help with simplest Quantum setup possible...

Well,

 Just for the record, I'll stick with Quatum + OpenvSwtich... Someone on IRC told me that it is the best way to go with Quantum.

 I'm still needing help to set it up (Single Flat / multi=false, still the same simplest topology).

 OpenvSwitch is already working, bridges `br-int' and `br-eth0' created...

 My main problem, I think, is that my Instances doesn't get an IP (they supposed to be at 10.33.14.X/24).

 Everything else seems to be working as expected, no apparent errors on the logs... quantum net-create / subnet-create worked...

 I appreciate any help, tips or docs!

Best!
Thiago

Hi!

 Sorry about the double posting... I need help!     :-P

 I'm trying, without any kind of success, to deploy OpenStack with Quantum on its simplest scenario, I think, which is `Single Flat' with `Linux Bridge' plugin.

 My topology is:

 1 firewall with 2 ethX (eth0 public, eth1 10.32.14.1 and 10.33.14.1)
 1 controller with 1 eth0 (10.32.14.232/24<http://10.32.14.232/24> gateway 10.32.14.1)
 1 node with 1 eth0 (10.32.14.234/24<http://10.32.14.234/24> gateway 10.32.14.1)

 Instances Network:
 10.33.14.0/24<http://10.33.14.0/24> (Instances gateway must be 10.33.14.1, same router of the physical servers above, NOT its own host hypervisor).

 I'm trying this:

 http://docs.openstack.org/trunk/openstack-network/admin/content/demo_flat_installions.html - doesn't work... Even enabling OpenvSwith (but I don't want it for now, only Quantum instead of nova-network, with Linux Bridge for the sake of simplicity).

 The following guide help me a lot (with Nova Network everything is fine): http://openstack-folsom-install-guide.readthedocs.org/en/latest/ - I'm trying to follow it, by replacing nota-network instructions, for Quantum instructions but, doesn't work...

 Any docs or tips?

 NOTE: I do not want any kind of NAT (like nova-network multi=true) or `Floating IPs' within my Cloud Computing environment.

Thanks!
Thiago
