as mentioned by povlhp - it doesn't work on VMWare. However I got it working on VMWare with this command:
sudo nvram boot-args="rootless=0"
and rebooting. I don't have Parallels on my home computer - but probably someone can give a try to it.
(If you have made some modifications like enabling TRIM on third party SSD, it's a good idea to check boot-args setting in nvram first. You can do it with command:
nvram -p | grep boot-args
If there is output - better do not experiment 
p.s. If you want to revert it, here is command as well:
sudo nvram -d boot-args
