Located on the far right of this picture (in the pink shirt,) I am a Fedora 9, 10, 11, and 12 user currently experiencing the x86 version. 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, RH253VT, and RH301VT coursework, in order to further establish my Red Hat educational foundation. My next training class will be the "Red Hat Enterprise Linux Update Course" - RHUP305
  • I 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:
    1. Left shows 1 VM with Fedora 11.
    2. Center shows 1 VM with Fedora 12.
    3. Right shows 4 VMs with 3 VMs on Fedora 9 and with 1 VM on Fedora 10.
  • Each VM has 1536 MB of RAM for execution and evaluation purposes within an established baseline VM system.
  • My latest Fedora 11 (Leonidas) kernels are vmlinuz-2.6.29.6-217.2.16.fc11.i586 and vmlinuz-2.6.29.6-217.2.16.fc11.i686.PAE. Good to see how in the Fedora 11 release, the iBus Intelligent Input Bus "input framework method system" and EXT4 file system "checksum feature for the journal" have developed.
This is a tip
My current workstation has eight (8) x86_64 computing cores and 16 GB of RAM as well as 500 GB harddisk (SATA Seagate 7200.12.) The Seagate 7200.12, 500 GB harddisk is only "one" platter and is very quiet as well as very low power consumption and fast for my use. I am considering a plan on doing an upgrade to the Seagate 7200.12, 1 TB harddisk in this calendar year.
This is important
A finding on my behalf regarding concurrent guest operating systems is to keep the ntp time clock in sync between the variety of guest VMs.
This is a note
The Fedora 11 version's "Swap" space is defined about 3 GB, versus the Fedora 9 and 10 versions' "Swap" space are defined about 2 GB.
