Thank you so much for your prompt response. I don't think I made myself very clear with my question. Sorry about that. This is all too new to me.
Here's the scenario. I have a laptop with Debian installed on it. I have been told to use two virtualization tools for this project: Vmware and Xen, both installed on Debian.
I would run each separately and run diagnostics on each. The idea is to virtualize a Windows Server and see each virtualization used more resources.
That's why I want to know if it is possible to install vSphere Hypervisor on Debian. Is that clear? Thanks a lot again.
