I am trying to integrate useful system administration ideas for my Fedora systems.


 * I am very interested in large memory model programs and multi-core computer systems. I enjoy using virtual machines (VMs) in order to develop a formidable system solution.  Through the use of VMs, I am able to try out a variety of software solutions on a VM prior to installation of the software on my production system.


 * I have taken RH033VT, RH131VT, RH142VT, RH253VT, and RH301VT coursework, in order to further establish my Red Hat educational foundation.


 * Recently, I have greatly enjoyed 24 hour access to the Live Access Labs running Red Hat Enterprise Linux 5. Now, I have the Red Hat Enterprise Linux 6 Beta running on a VM.


 * My next training classes will be the "Red Hat Enterprise System Monitoring and Performance Tuning" - RH442VT, "Red Hat Enterprise Security: Network Services" - RHS333, and "Red Hat Enterprise SELinux Policy Administration" - RHS429 as well as "Red Hat Enterprise Linux Update Course" - RHUP305


 * Currently, I am reviewing "Building a Secure Computer System" by Morrie Gasser at the http://www.cs.unomaha.edu/~stanw/gasserbook.pdf URL and "Security Guide A Guide to Securing Fedora Linux Edition 14.2" at http://docs.fedoraproject.org/en-US/Fedora/14/html-single/Security_Guide/index.html URL.

= Virtual Machine Information =

FYI on Virtual Machine Information integration

 * Each VM has either 3072 MB of RAM for i686 guest systems or 8192 MB of RAM for x86_64 guest systems as well as two CPU cores allocated for execution and evaluation purposes within an established baseline VM system.
 * My latest Fedora 12 (Constantine) kernel is 2.6.32.12-115.fc12.i686.PAE. I am very interested in progress in GRUB Ext4 support, NFSv4Default and NetworkManager System Connections
 * Good to see how the iBus Intelligent Input Bus "input framework method system" and Ext4 file system "checksum feature for the journal" have developed.
 * Very interesting to see how the Yum Langpack Plugin and the Udisks disk management improvements are proceeding.
 * When I have the VMs running with 1536 MB of RAM, I am able to enjoy using VMs for executing my Fedora 9, 10, 11, and 12 systems. With the effective use of VMs, I am able to concurrently run 9 VMs on my workstation.  There are three pictures at the bottom of this page:
 * Left shows 1 VM with Fedora 11.
 * Center shows 1 VM with Fedora 12.
 * Right shows 4 VMs with 3 VMs on Fedora 9 and with 1 VM on Fedora 10.

system core and memory utilization
With 2012, I am re-evaluating and determining how to best utilize the 16 cores and 80 GB of memory for effective systems. A periodic review of system resources is essential to providing an effective reallocation of system resources similar to the asset management theory.


 * Seven x86_64 systems with two cores each, running about 56 GB of memory. [[Image:Infra-icon_bodhi.png]]


 * Three i686 systems with two cores each, running about 12 GB of memory. [[Image:Infra-icon_cvssource.png]]


 * Total allocated memory for systems will be ranging at about 68 GB of memory and will leave about 12 GB of memory free and four cores for the host systems operations. [[Image:Infra-icon_bugzilla.png]]


 * Consider implementing High-Availability (HA) between the systems.

Fedora Purchases

 * I purchased my Fedora Polo Shirts here at, Custom-embroidered logo shirts and apparel by Queensboro located in North Carolina, for $9.95 each or Fedora Hat for $5.95, including shipping. The place is called, "http://www.queensboro.com/" use this information for the Fedora Logo.


 * I purchased my Fedora Buttons here at, Custom Buttons, Promotional Buttons located in Ohio, for $18.⁰⁰ (100 quantity,) including shipping


 * To facilitate phone calls around the world, I use unlimited world Skype for only $12.95 per month or free Skype to Skype chat, audio, and video for "Windows, Mac OS X or Linux" even for "iPhone."

Things I do

 * Both x86_64 and i686 versions of Fedora 9, Fedora 10, Fedora 11, Fedora 12, Fedora 13, Fedora 14, Fedora 15, and Fedora 16 DVDs and USB Distribution in Japan see Akihabara "Electric City" and The University of Maryland - College Park, Maryland
