Hi Sathiya, thank you for your reply, but please, i don't rely on know how to do that..forgive me for my ignorance... Can you please give me a hint ... thank you in advance
Please refer this article to create 2 separate virtual machines (After creating one virtual machine, repeat the steps to create the second virtual machine). Then you can start and work on both the virtual machines.
