When using NSX-T for networking in combination with NSX ALB for load balancing in the vSphere IaaS Control Plane, the ALB Service Engines attach to each Tier-1 Router (vSphere Namespace) with one vNIC. Naturally, there’s a limit of 10 vNICs per Service Engine, meaning we can connect up to 8 Tier-1 routers to one Service Engine, as one vNIC is needed for management and another for frontend traffic. We were curious to see how NSX ALB would handle more than 8 vSphere Namespaces in this setup. Read more

While I was testing Broadcom’s new Release 8.0.3, I encountered some issues getting my nested lab to work in a Proxmox environment. Despite enabling Nested Virtualization on all Proxmox nodes and setting the VM CPU type to ‘host,’ the vCLS service wouldn’t start due to EVC issues, causing DRS to malfunction. Troubleshooting Nested Virtualization First, I checked whether nested virtualization was enabled on the Proxmox nodes. This can be verified with the following command: Read more

VMware by Broadcom has recently released the “Consumption Interface” for the vSphere IaaS Control Plane (formerly known as vSphere with Tanzu or TKGS). This is a significant enhancement to the existing features of TKG, allowing for better management and visibility of your resources. With this new interface, you can now view and manage all your resources within vSphere namespaces directly from the vCenter GUI. This update simplifies the creation and updating of resources, enhancing the user experience. Read more

Identifying different applications running in the same Kubernetes cluster at an external firewall can be challenging. By default, all services running on a node are SNATed to the node’s IP address. With Antrea Egress we can make use of dedicated egress IPs for different Pods in a Cluster. If you just want to get to the quickstart, click here. What is Antrea? Antrea is a Kubernetes CNI which is currently a CNCF Sandbox Project. Read more
