RE[6]: Good direction from Microsoft

OpenVZ is not virtualization. It is OS partitioning. The same kernel is used for all the virtual instances.
We are talking about Hypervisor or VMM based Virtualization here.
To answer your question: ESX is not based on Linux. It uses Linux for initial boot and then for the management of it's virtual machine. But the underlying real kernel that is scheduling VMs etc is vmKernel. This is the reason it is not open source.

Actually if you have ever used ESX and installed it you would know that it runs on a stripped down redhat kernel.
That is how you can provision bare metal. VM doesn't have their own kernel for runnin on bare metal I am sure you know that.
Even the installer is based on Anaconda.
But Open VZ is open source and works well.
