Running a dedicated virtual machine for each user is very wasteful in
case when a user interactively and occaionally issues commands to R.
If a user needs only 100 MB of RAM at max, for free 3GB we will
satisfy only 6 of them. The VM will eat at least 256 MB as a minimum
requirement to run an OS. Consider also time to start up a VM,
managing lots of VMs for each user separately which will lie somewhere
on a HDD inactively taking also 1GB each (approx)

Kind regards,
