Dear,
Yes, VMware is the product which is basically in the market. I have installed and use once i mean about 2 years back.
Well, through my research, VMware is only good if your are in a "Tesing Environment". It is not recommended in the production environment. Because of following reasons,
It uses Kernel Resources upto high and u need very High End Server IF u are using 3 etc applications like (DNS, WEB, FTP), if the machine goes down all your three application goes down High Demanding of memory

Hello,
I work for a school in a New Zealand university and we are wanting to implement Server Virtualization for both CentOS and Windows systems. So I thought I would ask here what experience people have had with this and what issues that you all think should be considered?
Irrespective of which virtual server solution you choose be aware that virtualization brings with it steep storage requirements. Think of providing around 1TB of RAID10 storage for 20 guests. VMs do lots of tiny random IOs so for 20 guests split between 2 servers I provide 500GB of RAID10 to each via iSCSI SAN.
From my own research it seems that VMWare or Xen are really the two major products to be considered, are there any others I should be considering ?
Not really.
Is anyone running Linux "Guest" O/S's inside a Windows host ?? And if so can you share your reasons for this?
I do at work so I can prototype some Linux stuff on my Windows box.
Anyway thank you for your time and any experiences / knowledge you are willing to share :)
I would try both VMware server and Xen on CentOS, if you have 2 servers set them up side by side and plugged into your storage SAN. Run them through their paces, do some benchmarks get a feel for ease of use and maintenance.
When your ready and have a budget you can move up to the commercial versions, ESX and Xen Enterprise.
