If you still have the iso, setup a network install (requires another machine) by mounting the iso and exporting it as nfs. IIRC, the C5 installer won't support harddrive installs from media found locally. On another box: #mkdir /mnt/repo #mount -t iso9660 /Path-to/CentOS-5.4-x86_64-bin-DVD.iso /mnt/repo -o loop #echo "/mnt/repo/ *(sync)" >> /etc/exports #/etc/init.d/nfs restart now back at your new dual-AMD setup, grab the diskboot.img from the /images folder of the DVD/iso. either dd that IMG file to a USB flash, or boot it with syslinux/memdisk from a fat32 partition already existing on your new system (not likely), or burn the boot.iso to a CD (also found in images). Using a network install is much faster than via DVD. -- Mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

KVM by itself will not install a supporting br0 device. However Xen will. Unless you want to spend anywhere from 20min-2hours cooking up a DIY br0 install, install Xen no matter if you never intend to use it. KVM is meant to be used with Virt-manager although you can run qemu-kvm in its own console. Your success with KVM has a lot to do with your hardware. Intel (vmx) far and away has more bugs than AMD (svx) for some new guests like Win7 and Win2k8. Google around for kvm or Xen crashes (in Win2k8) for your intended CPU if it is an Intel vmx type. KVM is faster than qemu with kqemu-kernel and I've only come across one bug : the -usbdevice feature will not work in KVM but it works with qemu/kqemu. -- Mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] OT: piped greps with regex
List,
Happy NY.
>From the bash command below, I'm trying to parse out the startsector value:
$ sudo file mini_vusb.img
mini_vusb.img: x86 boot sector, Microsoft Windows XP MBR, Serial 0x25d84;
partition 1: ID=0xe, active, starthead 1, startsector 32, 390496 sectors
First try was with grep/egrep but I wanted to capture 'startsector 32' as a
group (). Nothing came close to working. Fail 1
Next attempt was with Perl
file mini_vusb | perl -lane '$i=0 ;for (@F) {print substr($F[$i+1],0,-1) if ($_
eq "startsector"); $i++}'
the above works, but it's too much fire power for the job :)
Actually I came up with it in a minute or two once I remembered the special var
@F. Success 1
Last effort led to this
$ sudo file mini_vusb.img | grep -Po 'startsector\s+\d+'| grep -Po '\d+'
32
I like this best. Is there a way to shorten it up?

[CentOS] acpi for Intel p45 chipset (C2Duo)
Hello, First time I install Centos (5.4) on a consumer Intel Motherboard. I've done 5+ AMD (am2 form factor) installs. The MB is Gigabyte ep45-ud3r with a CPU:Intel LGA 775 E7600 wolfdale I cracked the lm_sensors nut with 2 modules and lm_sensors from elrepo. The modules were kmod-coretemp kmod-it87 Now I'm trying to get cpuspeed to behave, or at least understand what it's doing. Here's my bios objects snip dmesg- $sudo dmesg | grep state ACPI: CPU0 (power states: C1[C1] C2[C2] C3[C3]) ACPI: Processor [CPU0] (supports 8 throttling states) ACPI: CPU1 (power states: C1[C1] C2[C2] C3[C3]) ACPI: Processor [CPU1] (supports 8 throttling states) -- unsnip -- In the advanced bios menu I enabled all the switches for CPU state management. If not enabled there is no acpi. My CPU is OC'ed to 3.74 Ghz The Intel state management hands it off to the kernel with max frequency of 2.8Ghz but bogoMips is unchanged and reflects OC'ed value. There are supposed to be 8 throttling states, but acpi-cpufreq (driver) only uses 3 states (1.6 Ghz - 2.8 Ghz). Has anyone found another driver to work better? I tried speedstep-centrino but it refuses to load. There is also p4-clockmod too, but I had doubts about it. Is this the best I can do? So far benchmarks are very good and the acpi power management does not hurt them. -- Mark ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Of course, Mock is not part of Centos base and you can't damage your install by using it, since it runs in a chroot. Use the latest version (which might be epel) and get the hang of it - you may not like using it.

The rpmforge repo is independent (but much loved) from Centos.
