CentOS 5 Beta

| |

Install CD BootInstall CD BootI discovered that CentOS announced a public release of CentOS 5 beta this morning. I quickly downloaded the 6 .iso images for the CDs and gave it a spin. The DVD iso is only available via .torrent and I can't do bittorrent at work.

Added to this release are package sets for:

Follow along with me as I do installs on both a physical machine and in VMware. Feel free to go directly to the screenshot gallery.

First Install - Physical Hardware

GUI Install SplashGUI Install SplashAfter burning all 6 CDs I booted from CD 1 and went through the install process. Since RHEL 5 / CentOS 5 are based on Fedora Core 6, if you've seen the Fedora Core 6 install, it is a lot like it. During the install I chose to customize the package set and added KDE and Virtualization... and then drilled down on a few of the other selected package set and added some individual packages. It told me I'd need all 6 CDs for the install.

Required CDsRequired CDsThe Install - The new graphics on the CentOS beta are very professional looking. It took about 20-30 minutes or so to do the install (I was doing other things and didn't swap out each CD immediately after being prompted). After the install it was time for a reboot and then firstboot. Firstboot was as expected...license, timezone, sound card config, firewall, SElinux settings, and create new user. The sound card config part had a volume control so I cranked it up which allowed me to actually hear the sample music over the cheesy internal speaker my test machine has.

GDM LoginGDM LoginGraphical Login and the Desktop - Then the graphical login screen showed up and I logged in the unpriviledged user I created during firstboot. I tried GNOME and then logged out and tried KDE. Both are the versions that were shipped with FC6 so they are fairly modern.

I'm guessing that since I picked the Xen kernel I didn't have the hardware accelerated options in GNOME to turn on wobbly windows and the 3D-Cube desktop. I'll have to try another install to find out for sure.

[Update: I did another install without Virtualization and made sure to add in compwiz during custom package selection and the "Desktop Effects" option was available and I turned on special effects. Bingo, 3D-cube desktop worked just fine although I turned off wobbly windows because I'm not fond of them.]

Virtual Machine ManagerVirtual Machine ManagerInstalling FC6Installing FC6Virtual Machines - I ran the Virtual Machine Manager which is a GUI admin tool to view, create, and modify virtual machines. I believe it supports Xen and Qemu. I decided to walk through the creation wizard and went through various dialog boxes to define the virtual machine. It let me pick a remote URL as the install media. Since I had chosen to create a para-virtualized machine, which does not require VT hardware support in the CPU (don't have it in the test machine), I had to pick a Linux distro that has been modified to work with Xen. In this case I picked Fedora Core 6 which I happened to have the install directory tree accessible over HTTP on one of my fileservers... so I plopped in the remote URL. I decided to create a image file (rather than use real disk partitions) of 10GBs and assigned it 512MB of RAM and 1 CPU.

GNOME DesktopGNOME DesktopKDE DesktopKDE DesktopAfter all of the parameters were satisfied, it booted a virtual machine and started the Fedora Core 6 GUI-based install in a new window. The Virtual Machine Manager window was still visable showing my real machine and the FC6 machine along with updating widgets showing the CPU and RAM usage for each machine.

The Fedora Core 6 install seemed to go at full speed and the install was done pretty quickly... at which time I clicked on the install's reboot button. It has been a while since I've used Xen so at this point, I'm not really sure what to do after the inital install of a virtual machine.

[Update: If you want to see some screenshots of using the Virtual Machine Manager to create a Xen guest, there are some on this page of Red Hat's beta manual.]

Install in VMware

The VMware install, from which the screenshots were taken, went exactly like the install did on the real machine... accept I didn't pick Virtualization... and I didn't have a sound card... and the default resolution for Xorg was 800x600.

Any questions?

Delay time when install centos on VMWare

Hi all,

I've install OS Centos on VMWare 5.0.0. I have one question for you. The clock is running very slow, 20 minutes per hours. Can you tell me know how can I do to overcome this problem.

Thank you,


Could it be your cmos battery?

Subject says it all..

Nope, it ain't the battery

What they are talking about is a time difference between the host machine's time (which I'm thinking is the real time) and the time the virtual machines running on that host think it is... and that the virtual machines keep loosing time as time progresses. They want the virtual machines to have the correct time... although I'm sure they want the flexibility to have a different timezone in each virtual machine.

Anyway, virtual machines loosing time is a long known problem for some hardware configurations and VMware. I think the recommended work around is to install ntp on each virtual machine and have the clock constantly corrected???

This problem never seems to

This problem never seems to go away. I have wrestled with it myself and am not 100% sure what I did to fix it. I had Fedora Core 5 for about a year originally installed from a demo version of VMWare's Workstation. Then from there I ran the image on other machines using VMWare Player. Then along came kernel 2.6.19ish and I was hit with the clock problem. I froze my kernel upgrades at 18 and was fine. I decided one day to try the latest and the problem was still there. Upgraded the Player and still didn't work any better. Installed Fedora 7 using VMWare Server then ran it at work using the Player and the latest kernels... all is well. So perhaps it's the kernel or the engine you used to create the image.

Hi Scott, Your blog about

Hi Scott,

Your blog about Xen looks pretty good ... and i'm trying to move to Xen when doing vm ... i'm wondering if you're able to create any vm using windows as guest os?
