I would recommend explicitly calling out what the hardware version should not be, to avoid any interpretation like- 11 or higher.

Can we say - "Node VMs should have Compatibility "ESXi 6.0 and later (VM version 11)".
We have not tested with any other VM compatibility yet.

@divyenpatel ESXi 6.0 and later implies ESX 6.5 too which by default comes with VM version 13. I think we can clearly only Virtual Hardware Version (VM version)
@prashima we have not tested VM version below 11 too. Anything higher than 11 isn't compatible. So I think we should particularly call out only version 11 . We need further testing to specify if anything below/above 11 is supported as well.

I suggest we reword as follows - Virtual Hardware Version (VM version) 11 & onwards is required for VMs serving as Container Hosts.

Once @divyenpatel files a tracker issue for Virtual Hardware Version 13 compatibility I suggest updating the known issues section to reflect that.

Virtual Hardware Version (VM version) 11 & onwards gives wrong message.
Virtual Hardware Version (VM version) 11 only works and tested.

* Node VM name requirements needed only until Kuberneters version 1.8.x.
- VM names can not begin with numbers.
- VM names can not have capital letters, any special characters except `.` and `-`.
