Gotta say, centos has been tough to install and get working. The anaconda installer makes large drive setups horridly tedious (especially if reinstalling a lot). Package selection seems a bit off... I did a virtualization package, no custom..did not install qemu, libvirt, and all attempts to do any virtualization failed due to non-installed packages. Then I decided to select all the virtualization packages in custom, but had selected 'web server' as the base package. I was never able to connect to the net here at home...apparently some things with 'modprobe' did not install and the eth devices 'does not exist' or something like that. Then I decided on the entire gnome package, with all the bells and whistles...everything worked, but who wants that? I removed some packages in gnome to see and reboot made machine dead. Did that 4 different times with very few package removals. Did a number of various tries with custom selections, but the dependencies seem to not be grabbing all it needs to work. Never got a non gnome setup to recognize eth devices (well, one time, but it never was able to get the net). I just installed a custom set up, all virtualization packages- virtualization selected as base. I added some gnome stuff and a few other doo dads.....booted up..went right to the command line.... no virt software works, errors everywhere. Display will not come up (x, vnc, or gnome no matter what).. Every installation, in first boot up had major missing or odd problems. One time I booted up with a gnome set up and selinux was stopping 5 differetn gdm programs..at boot...due to security risks... wtf? Any attempt to disable or make selinux permissive results in a dead machine, unable to ever boot again (left one up for 12 hours, never came back up, thought it was relabeling, but no message.) Removing packages with the gnome running only worked about 10% of the time, all others resulted in dead machine at reboot. I am considering, the only way to actually install and use this as a virtualized host is to go full desktop and hope the selinux enforcing will not break the system (with all the programs it will not let run on boot)... I have never, not once, been able to connect to the net in the command line setups...I know how to configure eths, network, dns, etc...not once, not even dhcp..config eth0 up, etc.. Gnome has not a single issue with the same exact file setups.. Many command line setups would not even see the eth devices, something about modprobe this or that not installed.....wth? quite an interesting task. I have now taken the server out of the center and am just going to endlessly install until I get a system that is low resources and actually allows the virtualization to work. My last install, with all virt packages selected...?..... cannot run virt-manager, libvirt, though some virt programs do work...why? something each needed to run was not installed as a dependency....<smacks head> Reinstalling would not be so bad, but the anaconda installer does not quite set up the drives the same on a reinstall forcing a deletion of partitions and redoing the entire setup..quite annoying /rant off

Not sure if it would be useful in your case. That said, I haven't had all the troubles you have on my sole C6 test server, before and after installing the desktop package.> Any attempt to disable or make selinux permissive results in a dead > machine, unable to ever boot again (left one up for 12 hours, never came > back up, thought it was relabeling, but no message.)This is rather odd, I only ever had problems with selinux set to enforcing. It should be relabelling if you had disabled it. Could there be some problem with your server hardware that's throwing you off with all these spurious problems?> I have never, not once, been able to connect to the net in the command > line setups...I know how to configure eths, network, dns, etc...not > once, not even dhcp..config eth0 up, etc..

Several of us were having problems until we switched to using the kmod drivers from elrepo.

You can also install centos using FAI (http://fai-project.org) which was announced in this mail: http://lists.centos.org/pipermail/centos/2011-September/117878.html It has a pretty nice partitioning tool called setup-storage which uses a configuration file similar to fstab. Here's one example. disk_config disk1 fstabkey:uuid preserve_reinstall:7,8 primary / 7G-15G ext4 rw,noatime,errors=remount-ro createopts="-m15" logical swap 2G-4G swap rw logical /tmp 3G-15G ext4 rw,noatime logical /srv 20G-30G ext4 rw,noatime logical /home 1G- ext4 rw,noatime,nosuid,nodev IMO it's much more easier to do the hard disk setup this way, especially if you do multiple installations. -- regards Thomas

Its model/chip and kernel log (dmesg) would be nice as well. In case this is Intel EXPI9301CTBLK NIC (according to your YT profile), which is seemed to be 82574L based, you should take into account known issues with stock e1000e module shipped with C6.0 [1] and that chip. //br 1. http://lists.centos.org/pipermail/centos/2011-September/118027.html
I downloaded a brand new file, made a brand new dvd. I then did an install selecting the virtualization package, then in custom I selected all the virt packages. During install did the same thing as 100 times before, including making netmanager turn on eth auto. it came up in command line, connected to the net, only error I can see so far in the dmesg is 2 things about composite sync or something like that... all other errors went away, installed the proper files to see my eths. I could even yum update from command line. I assume I must have had a bad dvd burn that corrupted a file somewhere. Instead of taking 3-5 minutes to boot up, it boots quick now. I was actually able to boot, play around, yum remove a few things, set selinux to enforce and permissive on different boot ups and it actually booted up. I gotta say the new dvd was 100% easy and no problems..the old dvd was giving me a unstable system. the composite sync thing seems to be a bug that can be changed in grub, so they say. Not even going to attempt to add x or graphics though, I guess you can install guests with text installer. Just no fancy lvm stuff for the guests... thanks ... it is up and running...finally...
