The Black screen is not letting me access anything, and It has already consumed about 30 minutes of my lab time
Hi Mohamed,
Have you gotten past this by now? Initially you want to start all VMs, don't start them individually. Once they are up restart individual ones as required.
In the appendix to the Lab guide there are some tips/tricks for working with the VMs. If you still experience problems, please contact me Denise.Cushman@ca.com and we will get you the support needed to continue with the course.
