Hi there, I have a lot of problems with RDO/OpenStack configuration.
Firstly, I need to describe my network situation.
I have 7 machine, each of them with 2 NIC. I would like to use one machine
as a controller/network node and the others as compute nodes.
I would like to use the eth0 to connect nodes to internet (and get access
by remote sessions) with the network "172.16.58.0/24", in which I have just
7 available IPs, and eth1 as configuration network on the network
10.42.100.0/42.
This is my current configuration, for each node (varying the IPs on each
machine):
eth0:
DEVICE=eth0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=static
IPADDR=172.16.58.50
NETMASK=255.255.255.0
GATEWAY=172.16.58.254
DNS1=172.16.58.50
DOMAIN=###
DEFROUTE="yes"
eth1:
DEVICE=eth1
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex
ONBOOT=yes
br-ex:
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=10.42.100.1
NETMASK=255.255.255.0
ONBOOT=yes
I'd like to have instances on 10.42.200.0/24 virtual private network and
the remaining IPs of 10.42.100.0/24 network as floating IPs.
These are the relevant parts of my answers.txt file:
CONFIG_CONTROLLER_HOST=10.42.100.1
CONFIG_COMPUTE_HOSTS=10.42.100.10,10.42.100.11,10.42.100.12,10.42.100.13,10.42.100.14,10.42.100.15
CONFIG_NETWORK_HOSTS=10.42.100.1

CONFIG_NOVA_NETWORK_PRIVIF=eth1
CONFIG_NOVA_NETWORK_FIXEDRANGE=10.42.200.0/24
CONFIG_NOVA_NETWORK_FLOATRANGE=10.42.100.0/24

CONFIG_NEUTRON_ML2_VNI_RANGES=10:100

CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=
CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1
After the installation, I configure the network like this:
neutron router-create router
neutron net-create private
neutron subnet-create private 10.42.200.0/24 --name private-subnet
neutron router-interface-add router private-subnet
neutron net-create public --router:external=True
neutron subnet-create public 10.42.100.0/24 --name public-subnet
--enable_dhcp=False --allocation-pool start=10.42.100.100,end=10.42.100.200
--no-gateway
neutron router-gateway-set router public
I'm able to launch instances but I can't get access (ping/ssh) to them.
I don't know if I'm doing something wrong starting from planning.
Please, help me!

Hi Pasquale,
Did you modify your security group rules to allow ICMP and/or 22:tcp access?
Many thanks

Hi Rhys,
I suppose so, because these are my iptables rules:

iptables -t nat -F

Firstly, do you think I planned the network organisation well? Do you have
other suggestion (best practices) with 2 interfaces?

Those look like the iptables rule on the hypervisor. Rhys is talking
about the Neutron security group rules. By default, ssh into VMs is
not allowed. You need to permit ICMP and SSH in the security rules on
the neutron network.
I don't see anything wrong with your network architecture at first
glance, but floating IPs can be tricky at first. Start with basic
VM-to-VM connectivity and add on from there.
Good luck!

Whops! I figured out just few seconds after I sent the mail! Ok, tomorrow
I'll try with it. :) I'd like to share how I want to organise my network in
order to get some advices.
Let's say I have 7 machines and 7 spare IPs on the network 172.16.58.0/24
which are also associated to 7 public (internet) IPs.
I'd like to reserve 6 IPs for 6 VMs I could instanciate on OpenStack.
So I planned to do this:
the controller node has a static IP on eth0 of the 7 in 172.16.58.50/24
network so as I can access it from outside. I add an alias eth0:0 with
which I connect the controller to the Management network of OpenStack, the
10.0.1.0/24 network. Also on the controller, I set statically the IP for
eth1 with one of float IPs network 192.168.0.0/16 network. With iptables, I
add the rule of forwarding everithing on eth0 and eth1, so the other nodes
can get Internet access on network 10.0.1.0/24.
On the compute nodes I set eth0 as one of IPs on 10.0.1.0/24 management
network and eth1 as one on 192.168.0.0/16.
Om each node I put the bridge on eth1.
With RDO I put virtualisation and tunneling only on eth1.
When the installatation has finished, I create a private neutron network
10.100.0.0/16 and two public networks of floating IPs. The first is
192.168.0.0/24 for any kind of VM. The other is the 172.16.58.0/24 network,
limited to the 6 available IPs with which I can put virtual machines on
Internet.
Does it make sense or I'm doing some mistakes? Do you have any other idea?
Thank you very much indeed!
Pasquale

Did you modify your security group rules to allow ICMP and/or

Those look like the iptables rule on the hypervisor. Rhys is
talking about the Neutron security group rules. By default, ssh
into VMs is not allowed. You need to permit ICMP and SSH in the
security rules on the neutron network.
I don't see anything wrong with your network architecture at first
glance, but floating IPs can be tricky at first. Start with basic
VM-to-VM connectivity and add on from there.
Good luck!

That sounds like it should work, but one of those 6 IP addresses will
need to be used for the Neutron router (that IP will be used for SNAT
for VMs that have no floating IP).
I'm not sure what you mean when you say "I'd like to reserve 6 IPs for
6 VMs I could instanciate on OpenStack." You can instantiate more than
one VM on each compute node, and if you have 6 compute nodes then
depending on size you could have dozens of VMs. Maybe you just mean
you could instantiate 6 VMs with public IPs? Actually, due to the
router IP, you would be limited to 5.
Make sure you add the floating IP network as an external net. Since
your router will not be taking the .1 address, you will need to create
the port by hand with the chosen IP and add it to the router.
$ neutron net-create externalnet -- --router:external=True
$ neutron subnet-create externalnet 172.16.58.0/24 --name external \
- --enable_dhcp=False --allocation_pool start=172.16.58.x,\
end=172.16.58.x --gateway 172.16.58.x
(use your network gateway here - change the IP addresses in the
allocation range to match what is available on your network)
$ neutron router-create extrouter
(name of your router)
$ neutron port-create externalnet --fixed-ip 172.16.58.x
(use desired router IP)
$ neutron router-interface-add extrouter port=$portid
(port id from previous command)
$ neutron router-interface-add extrouter subnet=public
(replace public with the name of the 192.168.0.0/24 network)
Once that is done, you should be able to assign a floating IP to any
VM that has an interface on the 192.168.0.0/24 network.
P.S. - Several times in your email you mentioned 192.168.0.0/16, but
that's not a valid network. I assume you mean 192.168.0.0/24.
