VMware Workstation Player (formerly VMware Player) is simple to use & easy to install on many Linux systems, especially the Ubuntu based ones, to include Linux Mint. Get it below. Make sure to get the Linux version, though there's one for Windows users also.
When downloaded, go to the Permissions tab & place a check in 'Allow executing file as program'
To install, simply open the Terminal & type in or copy/paste & press Enter after each, password will be needed on the 2nd.
Then the graphical installer will begin, skip the license key because this is a Free product. Now enjoy VM software that provides up to 2GB of VRAM (compared to 256MB for VirtualBox), and forget all of the silly 'rules' about connecting devices. Newly connected ones can be connected on the go!
BT connections also automatically shows. If one gives VMware Workstation Player a fair shake, it's unlikely the same will want VirtualBox any longer. Especially those who has computers loaded with resources. I have one W10 VM with 10GB of assigned RAM, 2GB of which goes towards VRAM. 8GB assigned to VM & 2GB assigned in the VM configuration. As an early bird Preview Tester for W10, ended up with a license that can be reused on that computer, and like other early Preview testers, was activated 7-10 days before latecomers.
Look at the power of VMware Workstation Player & decide for yourself.;-)
