I have been playing around with ProxMox, for my VM environment, and I am having a blast. I have Khali linux on it, Windows and Ubuntu. The ease of setting up VMs has just reached new levels from back in the day when I used to do it. Even Ubuntu has advanced so much since I used to use it like over 10 years ago. Although I am not a network admin, or a hacker, I do enjoy playing with things, and I have plenty of old laptops to do so.

I do wish there was more support for Linux, but I am thinking it is stifled by the big 2 not wanting more competition in the OS market. Never had the hate for Windows that others have, honestly I have more hate for Mac than Windows. Not saying Windows is a better environment than Mac, just saying I despise Apple and will never support any company made by Steve Jobs.
