Understanding Cluster Networking between Hosts
Hello everyone. I am looking to setup a ovrit cluster. I am struggling with the network side of things. I have watched some videos about Ovirt and kvm/libvirt. I understand the bridge and NAT networks. The part I am struggling with is the host network. Here is my setup. I have two bare metal servers, that have one physical nic with a public IP. There is no private physical network on these boxes virtual or physical. I want to host an application on a single vm for each customer. the customer access the application via username.domain.com. So the question is. I have to have a layer 7 load balancer to route the url to an IP. This load balancer is haproxy on a separate bare metal box. (it could be in a vm on one of the hosts) So the load balancer has to be on the same network as all the vms. I just don't know to setup the networking between the LB on one box and the vm's on potentially may bare metal hosts. It really feels like I am missing something really obvious. All the videos I have watched all assume the host networking is already in place. Any help or resources I can read/watch would really be helpful. Brad
Hi Brad, What are you using for storage, and are you trying to setup both of your physical servers into the same cluster? In my scenario (a hyperconverged environment with Gluster), ideally, you need two different networks, on separate network interfaces: One for your backend / storage network, and one for your frontend / VM network. In my case, I actually have 3 networks: * Backend Storage * IPv4 frontend traffic * IPv6 frontend traffic Sent with ProtonMail Secure Email. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Monday, October 18th, 2021 at 3:44 PM, <admin@foundryserver.com> wrote:

I will be using the gluster configuration, with 2 nics. I have just found a provider that will create my bare metal machines with two nics. I thought I would include a picture of what I understand about the setup of oVirt. I don’t know how to get the Load balancer to route traffic to the VMs that are on the 192 network. Brad
