Hi, I tried to execute the steps mentioned in [1] with master, minion-1, minion-2 and discovery on the following 2 PCs: - [M1] Lenovo 8GB machine with the following SW: - Ubuntu 14.04 - vagrant_1.6.5 - VirtualBox-4.3.20
- [M2] Mac 8GB machine with the following SW: - OS X 10.10.2 - vagrant_1.7.2 - VirtualBox-4.3.22 In addition, I tried to execute the steps mentioned in [1] with the 2VM setup (master and discovery) on the following PC: - [M3] Mac 4GB machine with the following SW: - OS X 10.8.5 - vagrant_1.6.5 - VirtualBox-4.3.20 The Kubernetes cluster did not get created. Therefore, after properly uninstalling Vagrant and VirtualBox, I reinstalled VirtualBox first and then installed Vagrant just to rule out all possible issues. However, I still am facing the same issue. I have added the output that I got from the [M3] machine as reference.
