Mouting Xen DomU images in Dom0
by Devraj Mukherjee 03 May '07

03 May '07

Hi everyone, I have a CentOS 5 Domain0 with a CentOS 5 Domain U installed on my machine, it all works flawlessly. One of the problems I am faced with is transporting the Domain U image to another machine (not in real time). Since the Virtual Machine Manager allows installing the guest operating system using the CentOS 5 installer, it ends up treating the partition (in my case an LVM partition) as a physical disk. To backup my Xen image is xm save the best way of doing it? Or can I infact mount the partitions created by the Domain U in Domain 0 and tar.gz them. Any feedback is welcome. -- "I never look back darling, it distracts from the now", Edna Mode (The Incredibles)

PearDB, PHP, CentOS 5
by Lonny Selinger 03 May '07

03 May '07

All, I'm trying to get a small app working but it requires DB.php provided by Pear. I've double checked and I have php-pear.noarch installed but there is no DB.php (just DependencyDB.php ). There seem to be no other packages that have pear or a DB.php file. Anyone have any ideas where I can get it? I've found just the files provided from the Pear site but I have no idea where to copy them to so everything is noticed properly. Suggestions/Solutions? Thanks!! Lonny

The Centos 5 install on my notebook stopped at 51% complete on downloading packages. Is there anyway to restart where it hung? Say boot into linux resumeinstall ? :) ARGH!!!

Rebuild all currently installed RPMs?
by Justin Cataldo 02 May '07

02 May '07

Hi there, Does anyone know a quick way in yum or rpm to reinstall all currently installed rpm's - ie: Some files have been deleted but you don't know which ones.. So you just want to force a reinstall of all currently installed. I have been using: Rpm -Va | grep missing >> missing.log And then more missing.log Rpm -q -whatprovides /path/to/file And then Rpm -Uvh --force ftp://mirror/path/file But it's a slow and painful process. It's on a CentOS 4.4 machine. JC

RE: [CentOS] Another CentOS 5 oddity: reboot and the X server fails tocome up

My server comes up in run-level 5 but I have to hit ctrl-alt-f7 to switch to the x-server screen. It doesn't switch to it automatically for some reason. Once I've changed to the graphical virtual screen everything else seems to work normally.

CentOS 5 dual head doesn't work
by Mark Hull-Richter 02 May '07

02 May '07

I just bit the bullet and installed CentOS 5 on my work desktop, and although I have two monitors and a card that supports them, I cannot get the display configuration to work with both as a continuous (spanning) desktop. I have tried using the correct (autodetected) monitor type (digital and analog), a generic LCD with 1280x1024, nothing works. Every time I set the configuration, the X server fails to restart and I wind up with single-head monitoring (duplicate displays on both screens). Here's what I have for an xorg.conf file (now): # Xorg configuration created by system-config-display Section "ServerLayout" Identifier "single head configuration" Screen 0 "Screen0" 0 0 InputDevice "Keyboard0" "CoreKeyboard" EndSection Section "InputDevice" Identifier "Keyboard0" Driver "kbd" Option "XkbModel" "pc105" Option "XkbLayout" "us" EndSection Section "Device" Identifier "Videocard0" Driver "vesa" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1280x1024" "1280x960" "1280x800" "1152x864" "1024x768" "800x600" "640x480" EndSubSection EndSection --- The strangest part is that system-config-display comes up with the right video card and the right monitor type, but I don't see either one here.... -- Mark Hull-Richter, Linux Kernel Engineer DATAllegro (www.datallegro.com) 85 Enterprise, Second Floor, Aliso Viejo, CA 92656 949-680-3082 - Office 949-330-7691 - fax Ask me about CentOS Linux, and escape from Windows forever!

Another CentOS 5 oddity: reboot and the X server fails to come up
by Mark Hull-Richter 02 May '07

02 May '07

I had to reboot my work machine today, and it came up in text mode (!). I did an init 5, but that had no effect (wrong command?). I killed the three gdm processes, and voila, X server mode. Where do I look to find out what is not right here? Thanks. -- Mark Hull-Richter, Linux Kernel Engineer DATAllegro (www.datallegro.com) 85 Enterprise, Second Floor, Aliso Viejo, CA 92656 949-680-3082 - Office 949-330-7691 - fax Ask me about CentOS Linux, and escape from Windows forever!

Centos 5 install on BIOS RAID ie. dmraid M/B
by Eugene Fong 02 May '07

02 May '07

I am experiencing hangs on the Keyboard Lang selection screen in GUI Mode install on a M/B setup with Intel BIOS SATA RAID. Workaround is to use 'linux nodmraid' switch which disables visibility of RAID volumes during drive detection of Disk Druid. Has anyone else tried this config without workarounds and success?

No grahical install on notebook with Centos 5, did work with Centos 4
by Robert Moskowitz 02 May '07

02 May '07

Hello again. Working to put Centos 5 on my old Toshiba Portege 3490ct (256Mb memory). PCMCIA CDrom and Lan card. Using 'linux askmethod' to be able to install off of my FTP server (have done 4 PC installs so far off that server successfully) It's video card is: S3 86C270-294 Savage IX/MV After recognizing the video card I get the message about no graphical install available. Putting on and external monitor does not change this. Problem with the character mode install is no LVM partition management functions. I need to alter the default partitioning. This IS an older notebook. It does have Centos 4.4 on it right now. How would I use the ftp install and specify 'acpi=no' (perhaps the old bios???). Or I could build a partial kickstart file on a diskette (add the USB diskette drive) to do the partitioning and then switch to package selection (and maybe even in graphical mode)? Some guidance here would be great.
