It seems as if WW2.15_Ubuntu20.04_Server.ova was built to support virtual machine version hardware 14 and below. VMWARE ESXi version 6.7u2 and newer supports version 15 or some higher version. On deploying the OVA, I receive error
Issues detected with selected template. Details: - -1:-1:VALUE_ILLEGAL: No supported hardware versions among [vmx-15]; supported: [vmx-04, vmx-07, vmx-08, vmx-09, vmx-10, vmx-11, vmx-12, vmx-13, vmx-14].
There is a lot of "self help" ways to crack open and edit OVA's with mixed results. If this is something easy to for maintainers to rebuild, or there is a new release coming down the road that can address this, let me know.
