Thanks for the information. Actually I followed Category 03 instruction. It went smoothly until install EBS and I got following errors. So, I removed all my installation (including Virtualbox) and trying to follow Category 04 (old) to install again. In my first installation (With Virtualbox – category 03) I noticed I can’t open internet browser. I used Firefox browser. Please let me know whether I need to go back to category 03 and how can I fix following issues?
