Re: [CentOS] error creating Centos 5.1 x32 dum_U instance on CentOS5.1 x64

Nah, RHEL 5.1+ supports 32-bit domU (PAE and non PAE) on 64-bit dom0.

question on how yum updates cache
by Rogelio 01 Mar '08

01 Mar '08

I'm trying to make sense of CentOS's package management based on what (little) I know about Debian's. When I do a "yum install program" and it takes forever, is it updating local cache to install the most up-to-date version of that program? When I do it in Debian, it seems to install whatever version is in the "apt-cache" (unless I "apt-get update").

Allocaation resource error (DELL Optiplex 755)...
by John.Giovannis＠csiro.au 01 Mar '08

01 Mar '08

Hi all, (My first time in seeking assistance via the CentOS mailing list ... Not sure if I should be submitting this as a possible kernel bug). I've successfully installed Cent OS 5.1 (kernel: 2.6.18-53.1.13.el5) on an Optiplex 755 (EM64T). However I'm not able to get a NVIDIA Gigabyte 8600GT (PCI-e) card to work with the system despite successfully installing the latest NVIDIA drivers (NVIDIA-Linux-x86_64-169.07-pkg2.run). I've tested the same configuration in Windows with no difficulties. I suspect the kernel is not able to allocate the appropriate hardware resources possibly resulting in the card failing to fire up properly: Some diagnostics: A snippet of the Xorg log file: # more /var/log/Xorg.0.log | grep -E 'WW|EE' (WW) warning, (EE) error, (NI) not implemented, (??) unknown.

CentOS Email Wiki and/or mailing list

As I see it, a mailsystem Wiki should have some specific divisions itself. One would be 'General' and then it would likely need 'Sendmail', 'Postfix', 'Qmail' areas. I'm just thinking out loud here. I've never done anything on a Wiki. I think a good initial layout however would be important. I'm trying to think about the gotchas I discover when trying to search for things. It seems like it always comes up two out of three and therefore isn't relevant. Sounds like I've just volunteered myself to participate in this Wiki! And yes, I'd be thrilled to! >> I think a fair number of the members of this list and the users of CentOS >> are using it in a server environment and require email.

Revisiting what I had been doing this past week took me down a few trails to not being satisfied with the end result. Hours spent to a dead end. There are many products out there and each seems to have some gotcha. It would be nice to know how well they get along with CentOS, how well they perform on various levels of load as well as results for accuracy in delivery. > We have plenty of resources within the CentOS setup.

IMHO, email is too niche an > area to have a dedicated list for it. Something like NetworkServices > might be a better target. I would be happy with anything! I always feel like I am off topic when posting email system questions to the CentOS list and I do think it is. NetworkServices could be a good place. I'm not sure it's the place for network hardware discussions... but I don't know. I haven't looked lately at how the mailing list are advertised. A good name for the list would certainly help it become more robust or having more users specific to that or those topics. Best, John Hinton

ACPI reboot-issue (CentOS 4)
by Simen Thoresen 29 Feb '08

29 Feb '08

Hi all, I'm trying to troubleshoot my way thru a ACPI-issue on several machines with the Asus P5N32-E SLI motherboard (S775, Nvidia 680i chipset) http://www.asus.com/products.aspx?l1=3&l2=11&l3=397&l4=0&model=1459&modelme… This is CentOS 4 x86_64, and appears on all tested kernels, including kernel-smp-2.6.9-67.0.4.EL My symptoms are that the machine won't reboot on the reboot command. 'poweroff' does turn the power off and halt halts the system (without turning the power off), but reboot effectively does a 'halt'. I can 'fix' this by giving the 'acpi=off' parameter to the kernel in grub, but this causes other problems (some of these machines have quad-core CPUs, and these require ACPI to initialize 3 of the cores. The dual-core CPU-machines work with acpi=off. With acpi=off, reboot works as it is supposed to. I think the root of this issue is the Asus BIOS - we also have several Asus M2N-SLI Deluxe (Athlon64, Nvidia 570 chipset) systems that started exhibiting the same symptom after a BIOS upgrade. On these acpi=off does not cause other problems, so this is no issue for us now. Any suggestions? I think I understand that turning ACPI off basically turns APM on, and that APM reboot works. Is there a way to do reboot with APM instead of ACPI? Yours, -S -- Simen Thoresen - Dolphin ICS Systems Administrator
