At the moment this KB has been wrote, API Gateway Appliance OVA it is supported only to work with ESX 5.x or ESX 6 hypervisor.
Importing the OVA into ESX 6.5, it would not work out of the box.
An OVA conversion must be executed before to import into ESXi 6.5.
In order for the following method to successfully convert the API Gateway 9.2 OVA to ESXi 6.5 compatibility you will require OVFtool version 4.2.2.
This software can be downloaded from: https://my.vmware.com/web/vmware/details?productId=614&downloadGroup=OVFTOOL420
Please note this method will produce an OVA that is only compatible with ESXi 6.5
Once this has been installed from a command prompt, run the following.
ovftool <current ova name> <new esxi 6.5 compatible ova name>
Here an example of the expected output:
./ovftool ~/gateway-9.2.00-6904-vmware-rhel-x86_64.ova ~/gateway-9.2.00-6904-vmware-rhel-x86_64-esxi65.ova
Opening OVA source: /Users/DOBBR01/gateway-9.2.00-6904-vmware-rhel-x86_64.ova
The manifest validates
Opening OVA target: /Users/DOBBR01/gateway-9.2.00-6904-vmware-rhel-x86_64-esxi65.ova
Writing OVA package: /Users/DOBBR01/gateway-9.2.00-6904-vmware-rhel-x86_64-esxi65.ova
The new generated OVA should be ready to be imported into 6.5 through the web based interface.
