I'm trying to bring up the edge cloud with 3 nodes (1 controller and 2 worker nodes) with starlingX 4.0 - distributed cloud.

Central cloud is up and running with All in One Duplex 2 controller configuration.

I was able to bring up the controller-0 in edge cloud using iso (virtual cd/dvd mount) and  was able to configure the personality for the other nodes as workers. But worker-0 and worker-1 are stuck in pxe boot for more than 2hrs. Any suggestions?

In "Standard controller with storage" configuration, is having 2 controllers compulsory ?

This document says it supports 2 controllers and upto 10 worker nodes.
