Try atop. There's an overview at https://lwn.net/Articles/387202/
It's available through the EPEL yum repository http://dl.fedoraproject.org/pub/epel/6/x86_64/repoview/atop....

I'm not sure what being on a VM has to do with anything.
It would be nice if there was a way (e.g. a command-line argument or atoprc setting) to disable the ability to kill processes from within atop; then it would be safer for an admin to make it executable as root by regular users.
For interactive use it is sufficient to install ATOP with the command (as root):
make install
I wouldn't have guessed the reference to root was optional! Thanks for the pointer.
