I was trying to install a vCenter for a lab on top of a ESXi 6.7 using the FREE license. Have verified several things:
- NTP was in place
- DNS records all good
- Enough resources
- Etc...
I realized that when using the FREE license on the ESXi hosting the vCenter appliance, seems that the installer can´t set the IP of the VCSA remotely using the OVA features. I just added a trial license back to the ESX and the installation worked.
I could not find any documentation on this: Software Requirements for the vCenter Server Appliance
Hope this helps,
Marcelo
