kvmw2130, can you confirm whether this feature is supposed to work with Instant Clone pools set to provision machines on demand? For me, it only works if I set the pool to provision all machines up front, which is not a good option for our use case. I have a separate thread about it here: https://communities.vmware.com/t5/Horizon-Desktops-and-Apps/Instant-Clone-Secondary-Image-Feature-No... 

Thanks!
