> AFAIK it's already possible but still experimental on Virtualbox, also it's hard issue to solve, and have tiny ROI I suppose. And why would they spent time fixing this slowness that only impact some small userbase like you?

It seems like you're just making guesses and don't actually know the answer? The reason I asked wasn't that I couldn't make the same guesses; it was that I had read online that there are technical obstacles here that (for reasons I don't understand, hence the question) they've had a hard time overcoming. i.e. "tiny RoI" or "small userbase" don't fully explain what I've read.

I was hoping someone would actually know the answer, not just make guesses I could have made myself.
