vSphere with Tanzu - Creating a Tanzu Kubernetes Cluster fails - Failed to deploy OVF package.

Creating a Tanzu Kubernetes Cluster fails. In vCenter server, the resource pool gets created under the namespace resource pool. However, the control/worker vms do not get created.

Creating a t0 edge in NSX-T to connect an internal physical network to an external physical network

Some notes from a recent lab I configured: My current lab looks like this -  I have few production VMs in one VLAN segment  External network access and Internet access is through another VLAN segment There is a jumpbox VM that is uplinked to both the VLAN segments. VMware vDS is currently being used and there are no free uplinks to make use of nvds. What do I want to accomplish?...
