Have you done the IAAS configuration manually  , just install a vannila windows server  after checking the compatibility matrix in vmware site . take a snapshot of the VM once done.

For IAAS strongly recommending you to install the OS from ISO (Please don't clone , if you are cloning you have to do the MSDTC uninstall re-install ) , 

Once the OS installation over , install all the patches using windows update and run this script https://github.com/vtagion/Scripts/blob/master/vCAC62-PreReq-Automation.ps1 .

While installing IAAS it will do a pre-requisite check and it will provide few of the blockages.

Few more things needs to check .

IAAS time , VCAC , SSO time should be equal and correct.

Since you are doing the Distributed Deployment ,  in Loadbalancer necessary port should be opened  and the loadbalancer virtual vcac fqdn you need to provide in IAAS installation.

Most important thing in IAAS installation all the components in vcac deployment reverse and forward lookup should work , or else you will end-up with error , please check this .

For all the componets and loadbalancer ip's do the nslookup FQDN and IP
