Which Virtualization to choose
Having small problem, reading for week various texts online, but still can't decide which virtualization is best for this situation:

System need about 36-48Gb of RAM (separated virtual machines 2GB RAm each) for working.

I have few multicore 16Gb-24GB servers.

What is best virtualization since every virtual machine will work 90% of time on 90% of load, where I can get best performance?

Virtal machines are UBUNTU. For now it looks to me that KVM is best solution, but not sure, can someone help me to choose, so again, questions is which virtualization will give me best performance for each VPS machine?
