Vmware Citrix Xenn virtualization on dedicated server

hi,
I am newbie and I think I am trying to bit off more than I could chew in this field. I would like to know if virtualization with Vmware Citrix on a dedicated server under ubuntu 64bit is simple.
I looked up in the board with keyword "virtualization, vmware, dedicated" but replied threads are not much.

Can anybody suggest me where to start from scratching this issue?
Can it be done by only system/network administator?

Thanks in advance

Hi,
I will buy a dedicated server and then I need to split total ram and HDD capacities into smaller pieces, I gotta attain different ip addressess and ssh passwords for each slice.
How can I do this? What are the requirements of a dedicated server to be able to do this with citrix.

Thanks in advance
