Redhat support switching between virtual terminal.
For some reason, sometimes under Red Hat it as been seen that switching from GUI to Console using
CTRL+ALT+F(number) stopped working for some reason. Assuming this is your problem, you may want to search on internet to find out how to fix that bug.
Under VMWare there are menu, you can try to look at them or press one of the F Keys (F8 ?) to have the VMWare popup menu. There might be restriction when you're in VMWare. Is it possible that CTRL+ALT+F(number) is mapped to other function in your linux (e.g. like shortcut ?)?
