End of Installation steps
Install VirtualBox:
Clint's modified set-by-step:: 
Do this first and the additional update will not be needed after adding the deb source: 
wget -q -O- | sudo apt-key add -
Open Settings |  Software & Updates |  Other Software tab
Click on the Add… button
Copy + paste the following line to the APT line box:
deb trusty contrib
authenticate as needed
Then Close and Reload
sudo apt-get install virtualbox-4.3 -y
cd Downloads
sudo usermod -aG vboxusers [your_userid]
reboot system
add virtualbox application to dock
open virtualbox appliction
File | Preferences | Extensions
browse to extension pack downloaded above
install and close
End of VirtualBox Installation
Demo setup of KDE Installation from DVD (Cancel and delete)
new | kde | 1024 | Create | vdi | Fixed | 12.00 GB |
Fixed disk creation takes a couple of minutes.
Insert Installation media (DVD) while waiting.
Or Maybe you should wait since mounting takes resources...
Click on Start
Browse to media location if necessary, Click on start.
Follow apppropriate steps to install your virtual machine...
(kde demo:  Click Install Kubuntu ... follow the bouncing ball.)
cancel and eject cd.
At this point, installation was cancelled in the interest of time and he imported a KDE machine virtual machine which he applied updates.
KDE Post Installation prep for Guest Installation:
    sudo -i | history <=shows current state of commands ran on KDE virtual machine. 
    1  apt-get update  (Done already)
    2  apt-get upgrade (Done already)
    3  apt-get dist-upgrade    <= installs header files for build
       downloads 62 MB. Lot less than the upgrade at 331 MB!
    4  reboot
    5. From Menu:
Devices | Insert Guest Additions CD image
Close Dolpin (FM) | Open terminal window |sudo -i
        cd /media/[userid]/VBOXADDITIONS_4.3.16_95972/
This may vary depending on your operating system
and version of VirtualBox Extension pack.
    6  ./ <= fails missing gcc
    7  apt-get install linux-headers-$(uname -r) <=if missing
    8  apt-get install gcc (12 MB download)
    9 apt-get install vim ctags vim-doc vim-scripts -y (optional)
    10./ <= success (takes sometime)
Create shared folder in the VirutalBox Machine Settings, select Shared Folders  
       create folder in home directory (KDEShare)
       Click add icon, browse to folder created and check both auto-mount, permanent options.

Early on we had a side discussion on the LVM disk management. Link provided this link for using LVM with VirtualBox:
Our next meeting on October 21st will be an open meeting (those always seem to work best), as there were no suggestions for a topic or program but suggestions are always welcome for something you would like to see and learn about in Linux or even better, something you would like to know.  Let us know at
