Fortunately, I had VMWARE Workstation License and Found some memories in IT storage room.
I passed VCP5 8,Nov 2013. and they sent me a mail for vmware workstation license.
If you don’t have VMWARE Workstation license, don’t be worried about it.
You can download “VMWARE Workstation Player, Oracle VirtualBox, QEMU, Windows Hyper-V, etc)
But, I recommend you to try VMWARE or Hyper-V first, if you are beginner.
They are well known products and everyone’s Q&A & experience(like me) will help you if you are good at searching in google . =)
Now, I had installed VMWARE Workstation and I’m ready to make virtual machines.
