What should I use as a VM environment/OS? Obviously I know GNU/Linux distros, but if all I'm going to be doing is using Firefox, I don't want a 8GB+ VM file hogging space on my normal system. Right now, I only have a 256 GB SSD in my laptop, and have my VMs on an external hard drive, which when plugged in to use uses up 1 out of my 2 USB ports. I would love to browse in a VM if I could get away without using a ton of space on my SSD. Also if you have any suggestions for options that also support high-DPI, that would be great, but not strictly necessary.
