I'm trying to install PacketFence on a virtual machine, and have dedicated 8 IPs to the server.
They all are static on eth1:0 -> eth1:7, so not eth1, eth2, etc.
When trying to configure vlans for "normal", "registration" etc. in Packetfence I get an error saying they need to be on different networks.
Can't I install Packetfence without physically separate networks?
The static routes use the same primary IP assigned to the device, so it might be a good idea to provision a portable subnet for your purpose.
Nevertheless, you could submit a ticket to SoftLayer, so that they might provide you further assistance.

I am trying to install openstack on a single node server.
I need to access Instances from internet.
I am new to openstack, so I spent some time trying to get it work correctly but without success. I tried devstack but it is not persistent after reboot.
For microstack, it is not configurable.
I need to assign Public IPs to instances. I have 2 physical networks. I tried with external network, but I don't found an option how to do that.
Did anyone successfully installed openstack on a single machine, and is there a way to expose instances to bring them puclic IPs from a pool.
Thanks in advance.
I'm trying to set up an Openstack environment with two Kubernetes clusters, one production and one testing. My idea was to separate them with two networks in Openstack and then have a VPN in front, to limit the exposure through floating ip:s (for this I would have a proxy that routes requests into the correct internal addresses).
However, issues arise when trying to tunnel requests to both networks when connected to the VPN. Either I choose to run the VPN in its own network or in one of the two, but I don't seem to be able to make requests across network boundaries.
Is there a better way to configure the networking in Openstack or OpenVPN, so that I can keep the clusters separated and still have access to all resources through one installation of OpenVPN?
Is it better to run everything in the same Openstack network and separate them with subnets? Can I still have the production and test cluster expose different IP-addresses externally? Are they still separated enough to limit the risk of them accessing each other?
Sidenote: I use Terraform to deploy the infrastructure and Ansible to install resources, if someone has suggestion in the line of already prepared scripts.
Thanks,
The solution I went for was to separate the environments with their own networks and cidr and then attach them to the VPN instance to let it get access to them. From there I just tunnel everything.
As far as I know, Openstack is a platform for virtualization and helps in efficiently creating and managing virtual machines. After creating two virtual machines on how can I use them or how can I deploy them? Can I access those instances from other locations in a network using their IP addresses?
Openstack allows to access instances from external network's also (external to openstack).
But it completely depends on the on your flat network ( floating Ip address network ) . if those are public IP's then you can access your instances from anywhere.
In Ceilometer, when pollsters collect meter from VMs, it used hypervisor on compute-node. Now, I want to write new plugin for ceilometer and not use hypervisor to collect meter, I want to collect meter by a service that is installed on VMs (mean ceilometer get data from service), so I need compute-node must communicate with VMs by IP (private IP). Is there any solution to do this?
Thanks all.
In general the internal network used by your Nova instances is kept intentionally separate from the compute hosts themselves as a security precaution (to ensure that someone logged into a Nova server isn't able to compromise your host).
For what you are proposing, it would be better to adopt a push model rather than a pull model: have a service running inside your instances that would publish data to some service accessible at a routeable ip address.
We have two physical system(ubuntu14.04.2) having 2 physical NIC each.
Is it possible to install openstack(juno) with neutron on same ?
Official documentation says that we need 3 nodes with network node having 3 NICs
Any help would be greatly appreciated.
Thanks,
Deepak
You can install all of OpenStack on a single system for development and testing purposes. Given that a single node installation is possible, it should follow that a two-node installation is also possible (and it is).
The documentation recommends three NICs because this leads to the simplest configuration. However, you can run a network host with two NICs. There are several different traffic types you'll be dealing with:
Public web (Horizon) traffic
Public API traffic (if you expose the APIs)
Internal API traffic
Tenant internal network traffic (traffic between Nova instances and the compute host)
Tenant external network traffic (traffic between Nova instances and "the rest of the world")
Storage (transferring Glance images, iSCSI for Cinder volumes, etc)
Being able to segment these in a meaningful fashion can lead to a more manageable and more performant environment. With only two NICs, you are probably looking at one for "internal traffic" (interal api, storage, tenant internal networking, etc) and one for "external traffic" (dashboard, public apis, tenant external traffic). This is certainly possible, but it means, for example, that excessive traffic from your tenants can impact access to the dashboard, and that a high volume of storage traffic can impact access to Nova instances.
If/when your environment grows beyond two nodes, you may want to investigate adding additional NICs to your configuration.
