I used  system-config-lvm to create space on the primary volume, where I
have Ubuntu 14 installed.  However I can still not install a second
operating system there.  I tried using the installer and gparted.  Would I
need to use gparted installed on a usb drive to get it to make that second
logical volume useable?  Or something else?
