Curb Your Enthusiasm, ESXi RCLI’s APIs not really open yet!
It has been blogged all over the place that VMware has enabled the RCLI Read/Write on the latest update of ESXi, but it seems that this was done by mistake. Mick D updated this on his blog and it seems that we won’t be playing or coding with these APIs since they’re going to be closed in the next ESXi update.
