I'm thinking of installing a virtual machine on my linux (centos 5.x) box. I'm wondering which virtual machine should I get: virtualbox, parallels, vmware.
2) What's the most efficient?
3) I have my centos server running. Will I be able to run my server with no downtime while running the virtual machine at the same time?
The linux box is I think a black edition AMD 2.0 ghz and 4 GB RAM. So I think it should be sufficient to run both at the same time. Thanks,
