There's no reason to try to do this using ESXi, and the fact that someone would be stuck on using ESXi is the reason I became suspicious that you were trying to mine on a company's servers. In that case I imagined your company had ESXi servers, and you wanted to mine on them, so you had to work backwards from ESXi. I doubt anyone would be dumb enough to do that. Well, no, scratch that. I am not accusing you of doing that. But there has actually already been one case in the media of someone being prosecuted for mining on his employer's servers.
There was also a university that sued someone a few years back for running distributed computer (one of the scientific ones, like Distributed.net or something). They sued him for retroactive back-pay too, for all the months of increased electricity and heating costs he caused them by running the distributed app on hundreds of their computers.
Text never translates well. Your post was not negative and you misunderstood me. It doesn't matter.
