I also haven't using Xen :-) so I searched it, and it seems like that
+------------------+
|   application    |
+------------------+
|      Docker      |
|       Xen        |
|       KVM        |
+------------------+
| hardware machine |
+------------------+
Docker has higher utilization rate of resources, such as memory and hard 
disk sharing, and KVM isolation is more thorough.
So Docker is on application layer, and it is easier to manage a bunch of 
application containers.
If you prefer standalone virtual machine, KVM and Xen is better.
But I'm not sure which is better between KVM and Xen, seems KVM is more 
widely used at present.

And I forgot ESXi need a license key for your multi core machine, sorry.
