Okay, The main purpose is to LEARN about virtualization and play around with it. However,I have a problem of determining which is best for a HEADLESS server. I want to run several Linux distributions as guests and of cause Windows guests as well.

On a Side Note: This is not the first time I am going use virtualization. For more than 3 years I have been using VMWare Workstation and VirtualBox to run guest VMs

However, now I want to run VMs/VEs in a headless server as they do in industry. I know, in industry there are lot of advanced technologies are being used but, still I want to try them in SMALL-SCALE. As I mentioned before, this is purely for educational purposes.

If you’re wondering what kind of system that I am going to use as my host, here are some details:

Intel processor that supports hardware virtualization (Intel-VT)
8GB RAM
More than enough Hard disk space (~1TB)

THEREFORE, CAN YOU GUYS GIVE SOME SUGGESTIONS / LINKS TO TUTORIALS etc. Your ideas/help is very much appreciated.

Thank you in advanced.

P.S. I installed VMWare vSphere Hypervisor on my "host" and later noticed that it uses just over 1GB of my RAM just to run hypervisor. It is not an efficient solution for me because I have only 8GB RAM in my machine. Typical Linux Headless server only uses ~300MB RAM just to run. So, I prefer Linux Server. In fact I love FOSS

I am moving to Germany on Saturday, and I was wondering how to unlock my Droid 2 Global so that it works with networks over there. I currently have Verizon, but I don’t want to have an international plan through them for the next 3 years.

My verizon wireless contract has been over for about 3 years. I want to get an iphone but I was wondering if I could get it for a cheaper price since my contract is over.

I’ve had my MacBook for about 3 years now, and lately I started to notice that it’s becoming a little slower than it’s normally been. I know on PC’s, there’s ways to clear unused space from your computer, and such. Is there any thing I can do with my Mac that would do the same thing, or anything else that could do to make my Mac a little more faster? Any tips would be greatly appreciated.

My macbook’s around 3 years old now. I left my macbook on and after like 15 min i thought it went on screen saver. I pressed enter to wake it up and it didnt so i pressed the power button. It still didnt work. What should i do?
