Your question is not that clear. Are you new to the field and want to know what are the product and services that are available in the market or just want to test if you are the only person to know virtualization here at sajha. Your question is not clear as other members have mentioned.

If you want to know about my environment I am using vmware on my vista machine at home. I have debian, solaris, redhat, mac os x, windows 2008, ubuntu, suse and on the other hand I am using solaris sparc system using zones and containers. I am also using LDOM on sun sparc T series processor.

If you mention what you really looking for I think you will get solid answer here.
