I and 3 my friends are going to buy a large dedicated server around $110 / month with specs
And we want to split it into multiple smaller ones? is it possible to do that?
I have heard of Xen, KVM or Open VZ to do that, do I need a web hosting expert for this job?
Any advice?
Sure you can. All 3 of the virtualization platforms have their own strengths and weaknesses.
Are you wanting the virtual machine for yourself or do you plan on offering VPS's to others?
If they are for others, do not use OpenVZ as most people these days are looking for XEN or KVM so they get dedicated resources.
Where are you getting the server from? That is a pretty low price for those specs. Keeping costs down is good, but make sure it is on a network with no single point of failure and with a company with really good tech support. Otherwise, you can get everything finally setup just the way you want it, and loose it all in the blink of an eye. Network hardware & servers fail. It's not if, it's when!
You do not have to be a web hosting expert to provision a server into VM's, but it also depends on what your going to do with them. If you can tell us more about your plans we may have more advice for you.
