(5.6) Kernel Link Error
by Always Learning 13 Sep '11

13 Sep '11

Installing VirtualBox-4.1* on Centos 5.6 X64, I get at the end:- Error! Your kernel headers for kernel 2.6.18-274.el5 cannot be found at /lib/modules/2.6.18-274.el5/build or /lib/modules/2.6.18-274.el5/source. In /lib/modules/2.6.18-274.el5/ I find two broken links:- build -> /usr/src/kernels/2.6.18-274.el5-x86_64 source -> ditto The reason why they are broken appears to be the current address is actually /usr/src/kernels/2.6.18-274.3.1.el5-x86_64 Show I reset the links in /lib/modules/2.6.18-274.el5 to point to /usr/src/kernels/2.6.18-274.3.1.el5-x86_64 or is their a bigger problem that needs attention ? -- With best regards, Paul.

CentOS 6, Broadcom, missing wlan0
by Michael D. Berger 13 Sep '11

13 Sep '11

This is a continuation of my previous thread: "Broadcom Wifi Problem" Following a post from "James A. Peltier", who said: You can use the rpmforge version or compile it yourself. I've used this one with success using the details described earlier. http://www.broadcom.com/support/802.11/linux_sta.php I did however have to patch it with http://www.broadcom.com/docs/linux_sta/5_100_82_38.patch the driver built and installed fine. In fact, I'm using it on my laptop as we speak. On my CentOS 6, with BCM4311 802.11b/g. I installed: hybrid-portsrc_x86_32-v5_100_82_38.tar.gz With NetworkManager shut off, I see: #lsmod | grep "b43\|ssb\|wl" wl 2635904 0 lib80211 4858 1 wl and I try to start with: ifup wlan0 I put debug in the script, following into nested scripts, and see that it ultimately fails because: ip -o link fails to return wlan0 . I rechecked the MAC address, which is correct. Also ifconfig and iwconfig do not see wlan0 . Also, the wlan0 light on the box doesn't turn from red to green. If, however, I reenable b43, the light does turn green. Also, on this dual boot box, the WinXP partition runs WLAN0 with no problem. Thanks for your suggestions. Mike.

Installing RPM using --prefix and possible libvirt patch
by Trey Dockendorf 12 Sep '11

12 Sep '11

I'm trying to install libvirt to /opt/libvirt, in order to test a patch I've worked into the current release, but it seems RPM is ignoring the --prefix command. The RPM I built has "Prefix: /opt/libvirt" in the spec, and correctly shows as relocatable by RPM... # rpm -qpi libvirt-0.8.1-27.el6.6.x86_64.rpm Name : libvirt Relocations: /opt/libvirt Version : 0.8.1 Vendor: (none) Release : 27.el6.6 Build Date: Fri 09 Sep 2011 07:30:28 PM CDT Install Date: (not installed) Build Host: itsclinuxdev.tamu.edu Group : Development/Libraries Source RPM: libvirt-0.8.1-27.el6.6.src.rpm Size : 2538412 License: LGPLv2+ Signature : (none) URL : http://libvirt.org/ Summary : Library providing a simple API virtualization Description : Libvirt is a C toolkit to interact with the virtualization capabilities of recent versions of Linux (and other OSes). The main package includes the libvirtd server exporting the virtualization support. However when I issue the RPM command it will throw errors about conflicting with the current install of libvirt. # rpm -ivh --prefix /opt/libvirt libvirt-client-0.8.1-27.el6.6.x86_64.rpm Preparing... ########################################### [100%] file /usr/lib64/libvirt.so.0.8.1 from install of libvirt-client-0.8.1-27.el6.6.x86_64 conflicts with file from package libvirt-client-0.8.1-27.el6_0.6.x86_64 file /usr/share/man/man1/virsh.1.gz from install of libvirt-client-0.8.1-27.el6.6.x86_64 conflicts with file from package libvirt-client-0.8.1-27.el6_0.6.x86_64 file /usr/share/man/man1/virt-pki-validate.1.gz from install of libvirt-client-0.8.1-27.el6.6.x86_64 conflicts with file from package libvirt-client-0.8.1-27.el6_0.6.x86_64 file /usr/share/man/man1/virt-xml-validate.1.gz from install of libvirt-client-0.8.1-27.el6.6.x86_64 conflicts with file from package libvirt-client-0.8.1-27.el6_0.6.x86_64 The patch I worked into libvirt is here, http://www.redhat.com/archives/libvir-list/2010-July/msg00480.html (not my posting), to add ESXi and ESX 4.1 support , in my case to virt-v2v. I'd like to install it without possibly breaking my current install of libvirt and just use the patched virt-v2v binary. As a side note, where should I direct my patch to possibly have it put into the official centos release? I had to slightly modify what was posted in the above link to make it work with 0.8.1. Thanks - Trey

lftp mirror replication
by John R Pierce 12 Sep '11

12 Sep '11

so I have an internal mirror I was replicating off mirrors.kernel.org via lftp, using a script... /usr/local/bin/lftp -c 'open ftp://mirrors.kernel.org/pub/ && \ lcd /export/mirror && \ mirror --continue --verbose=1 -x ia64 -x s390 -x s390x \ -x alpha -x SRPMS centos' well, kernel.org is down now, due to their being hacked, grrrr. if I switch this to another source archive, will it 'just work' or will there be any differences in the file dates that will end up causing massive new downloads of the same data? and, is it just me, or is the mirror list on http://www.centos.org/modules/tinycontent/index.php?id=30 a lot smaller than it used to be? -- john r pierce N 37, W 122 santa cruz ca mid-left coast

Installation on Intel DH67BL motherboard failed
by Sanjay Arora 12 Sep '11

12 Sep '11

Hello all I tried to install Centos 6 on Intel DH67BL motherboard with i7-2600 processor and a PCI Parallel/Serial port Card. This machine is running Win7, Ubuntu & Fedora 15. Booting from DVD, the machine boots up in text mode & loads vmlinuz and then the screen goes grey. Pressing a keyboard key does some dvd/hdd activity, so the machine is not hung. So the issue is obviously the graphics chipset. Research in CentOS forums shows that this may be supported by CentOS 6.1 machine. Can I install graphics/network support from some other repo, till 6.1 arrives and then again I can reinstall with only CentOS repos. My skillset is limited to compiling from source if instructions are there, but not trial & error otherwise. Any pointers? With best regards. Sanjay.

disk duplication question
by Jerry Geis 12 Sep '11

12 Sep '11

I have need to duplicate centos 6 on 133 computers. I purchased a disk duplicator make my master and the duplicator does 11 at a time. All is good so far... When I take a duplicated disk and stick it in the "new" box which is different than the master machine of course all seems to work except the network. So of course the MAC address for the NIC doesn't match so the network doesn't work. My solution was to edit ifcfg-eth0 and remove the HDADDR line and edit udev/70-persistant-net.rules and remove the MAC address from the network SUBSYSTEM line. The network does come back on and everything seems fine. Is this the correct way to do this? Making a master and being able to stick the duplicated disk in another machine? Thanks, Jerry

Alexander: The she is actually a he :) > Quite right, sorry, I'd read it backwards. So presumably either a bug > in the > AHCI support, or a limitation/bug of the kernel driver? > jh John: Actually, this is a complete false alarm. Actual Solution: You don't have to change anything on these laptops. But it is a good tip that when installing from external cd/dvdrom, if it first does not work, change usb port and try again. I changed back the BIOS to AHCI. I was previously plugged into the top left USB port I.e. the one on the left hand side closes to the monitor or back side. When lenovo's external CDROM/DVD is plugged into this port, I am unable to install linux in general or other OS's. Once I plug it into any of the other USB ports bottom left or right, it works perfectly. No wonder I haven't found any problem posts regarding x220 and CentOS/RHEL. Thanks for all your time supporting me. Fantastic responses on this mailing list. Use external CD/DVD ROM, just ensure to plug it into the right port :) Cheers, Janne "Janski" Nyman E: jnyman(a)jbtec.org
