rhel6 normally DOSE NOT install a gui
a gui is not wanted on a server
you would have to install gnome
gnome is not installed by default on a server
Did you install Gnome?
If you installed gnome then
from the link above
http://docs.redhat.com/docs/en-US/Re...oting-GUI.html
edit "/etc/inittab " with nano or vi
and change "id:3:initdefault:" to "id:5:initdefault: "
gedit will not work without gnome running
also gnome is started by using GDM and not startx any more
after loging in as a NORMAL user and NOT as root
type in gdm
also seeing as this is a VM install on an Oracle( was sun) Solaris have you looked on the Oracle VM web site
