==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, [[Features/NFSv4Default|NFSv4Default]] and [[Features/NetworkManagerSystemConnections|NetworkManager System Connections]]
* Good to see how the [[Features/IBus|iBus]] Intelligent Input Bus "input framework method system" and [[Features/Ext4DefaultFs|Ext4]] file system "checksum feature for the journal" have developed.
* Very interesting to see how the [[Features/YumLangpackPlugin|Yum Langpack Plugin]] and the [[Features/UdisksImprovements|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:

===system core and memory utilization===
With 2017, another 24 cores and 192 GB of memory. Before I had been re-evaluating and determining how to best utilize the 96 cores and 336 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.  [[Image:Infra-icon_koji.png]]
 
* Seven x86_64 systems with two cores each, running about 112 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 124 GB of memory and will leave about 8 GB of memory free and four cores for the host systems operations.  [[Image:Infra-icon_bugzilla.png]]
 
* Eight x86_64 systems with two cores each, running about 128 GB of memory.  [[Image:Infra-icon_bodhi.png]]
 
* Two i686 systems with two cores each, running about 8 GB of memory.  [[Image:Infra-icon_cvssource.png]]
 
* Total allocated memory for systems will be ranging at about 136 GB of memory and will leave about 56 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.

About Dramsey

Email: MailTo (dramsey AT fedoraproject DOT org)

Dramsey with friends

Located on the far right of this picture (in the pink shirt,) I am a Fedora 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 and 26 user currently experiencing the x86_64 and i686 versions. 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.

x86_64 and i686 kernels

January 03rd, 2011 Conceptual Drawing of x86_64 & i686 Interoperability

Where I get my x86_64 and i686 kernels - http://koji.fedoraproject.org/koji/packageinfo?packageID=8 Good information on http://kernelnewbies.org/LinuxChanges about Linux Changes especially the Linux 4.11 kernel.

system core and memory utilization

With 2017, another 24 cores and 192 GB of memory. Before I had been re-evaluating and determining how to best utilize the 96 cores and 336 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 112 GB of memory.
  • Three i686 systems with two cores each, running about 12 GB of memory.
  • Total allocated memory for systems will be ranging at about 124 GB of memory and will leave about 8 GB of memory free and four cores for the host systems operations.
  • Eight x86_64 systems with two cores each, running about 128 GB of memory.
  • Two i686 systems with two cores each, running about 8 GB of memory.
  • Total allocated memory for systems will be ranging at about 136 GB of memory and will leave about 56 GB of memory free and four cores for the host systems operations.
  • Add additional resource diagrams.
  • Place SELinux reference URLs, here.
  • Place Virtual Machine description URLs, here.

Some system information

Food for thought

This is a tip
My current workstation has eight (8) x86_64 computing cores and 16 GB of RAM as well as four 500 GB harddisks (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 next calendar year. Another workstation has arrived with eight (8) x86_64 computing cores and 64 GB of RAM.
Another tip
Google's IPV6 web site - http://ipv6google.com/ try it.
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 something else important
Fedora 12 Alpha with 3072MB of RAM. After that amount of 3 Gigabytes (GB) RAM, the 32-bit kernel is abending. Also, the "Swap" space is defined about 4 GB.
This is a note
The Fedora 11 and Fedora 12 Alpha version's "Swap" space are defined about 3 GB, versus the Fedora 9 and 10 versions' "Swap" space are defined about 2 GB when all versions were provided 1.5 GB of RAM.
This is an additional note
At this time, I am not really very impressed with the dracut product. The dracut execution time was about 15-25 minutes to update my kernels dependent on the virtual machine being used. As of September 22nd, 2009, I have used dracut about 40+ times. Maybe when the F12 Beta and/or F12 Final Release are made, dracut will be better. Update, with F12 Beta and RCs, the dracut execution time is now about 2-3 minutes.
This is a warning
A little FYI on updating to the 2.6.31-2.fc12.i686 and 2.6.31-2.fc12.i686.PAE kernels, a separate rpm install was needed of the bindutils-2.19.51.0.14-31.fc12.i686.rpm package from the original install media's iso, in order to address the bindutils dependency prior to updating to the 2.6.31-2.fc12.i686 and 2.6.31-2.fc12.i686.PAE kernels.
This is a caution
Currently, the Virtual PC 6.0.156.0 and the F12 Alpha iso are having some serious problems with getting X to work. Therefore, my /etc/inittab file on those test subsystems is set to run at runlevel 3 instead of 5.
