2015-06-20 09:08:26 -0500 commented answer Packstack answer file - sorting out interfaces

Sorry, but

CONFIG_NOVA_COMPUTE_PRIVIF is eth1 on your compute node(s)?
CONFIG_NOVA_NETWORK_PUBIF is eth0 on your network node?
CONFIG_NOVA_NETWORK_PRIVIF is eth1 on your network node?
CONFIG_NEUTRON_OVS_TUNNEL_IF is eth1 on your compute node or network node?

Thanks, but I would still not understand to which server's NIC the config value is referring.

CONFIG_NOVA_COMPUTE_PRIVIF=eth1 (eth1 on which server?)
CONFIG_NOVA_NETWORK_PUBIF=eth0  (here?)
CONFIG_NOVA_NETWORK_PRIVIF=eth1 (here?)
CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1  (and here?)

HI all,

I'm trying to set up a multi-node configuration using RDO on CentOS 7 using openstack-kilo. I'm confused by which interface goes where in the answers file.

My network is set up following this diagram: image description

Right now, I have these interfaces specified, but I don't think it is correct.

CONFIG_NOVA_COMPUTE_PRIVIF=p4p1
CONFIG_NOVA_NETWORK_PUBIF=p4p2
CONFIG_NOVA_NETWORK_PRIVIF=p4p1  ???
CONFIG_NEUTRON_OVS_TUNNEL_IF=p4p1  ???

Also, where would I specify ens1 and ens2?

Thanks! (and thanks to someone for the base diagram)

2014-12-11 08:25:37 -0500 answered a question Networking on single server - RDO on CentOS 7 w/ public ip subnet

I actually got this working, but it was more trial and error than good debugging skills (cuz I am a total noob and the target is moving faster than the available docs).

I went back to:

CONFIG_PROVISION_DEMO_FLOATRANGE=a.b.c.160/27

and then built the public network as admin specifiying:

(keystone_admin)]# neutron net-create --shared --router:external=True public
(keystone_admin)]# neutron subnet-create public a.b.c.160/27 --name public_subnet \
                                 --enable_dhcp=False \
                                 --allocation-pool start=a.b.c.164,end=a.b.c.190 \
                                 --gateway=a.b.c.161
(keystone_admin)]# . keystonerc_demo 
(keystone_demo)]# neutron router-create demo_router
(keystone_demo)]# neutron router-interface-add demo_router private_subnet
(keystone_demo)]# neutron router-gateway-set demo_router public

Following that, I demo had ports to which I could attach floating IPs and I could ping/ssh in and out.

Note: the important thing was getting the host network and public network (inside openstack) on the same subnet (but not including the host's IPs in the allocation pool), and then doing the steps above using the right keystone user for each step.

Hi all,

I've leased a dedicated server from a US based datacenter. I'm trying to get RDO up and running, on top of a fresh CentOS 7 install (+ updates).

The server is nice and beefy, with two wired NICs, plenty of CPU and memory for testing and learning. Potentially, I'll do a migration from an ESXi server to KVM instances on this box. I have been issued a /27 public subnet by the DC and need this to get into the server and for floating IPs.

I started with a packstack --allinone install and have tweaked the answer file to provision the higher /28 of this subnet for floating ips.

So, for my physical NICs I have:

subnet a.b.c.160/27
Gateway: a.b.c.161
eno1: br-ex
br-ex: a.b.c.162
eno2: a.b.c.163

(a.b.c are some actual public ip block values)

This works fine. I can ssh into either ip on the host itself.

In my answers file:

CONFIG_CONTROLLER_HOST=a.b.c.162
CONFIG_COMPUTE_HOSTS=a.b.c.162
CONFIG_NETWORK_HOSTS=a.b.c.162
CONFIG_STORAGE_HOST=a.b.c.162
CONFIG_AMQP_HOST=a.b.c.162
CONFIG_MARIADB_HOST=a.b.c.162
CONFIG_MONGODB_HOST=a.b.c.162
CONFIG_PROVISION_DEMO_FLOATRANGE=a.b.c.176/28

First, does this sound like a good approach?

And second, I've been stumbling a lot with associating an IP to my first (demo) instance ("no available port"), and also with ping from the host to the guest VMs, though the guest instance does seem to pick up the 10.0.0.0/24 ip. Any ideas on that?
