similar to: how to delete a trashed kernel

I have a screwed up disk arrangement, but I have had no trouble because of it after using it over a year. Recently I did a yum update. After starting the update, which included a new kernel, it seemed to either freeze or loop. It was a long time at the? prompt and I got impatient and did a Ctrl C. I then tried to re-boot. The result was a kernel panic. I am keeping 5 kernels and when I select? the

Hello there, the *old* PC (Turion 64 MT-32 800MHz, 1Gb RAM) of my gf is running Windows XP, and I plan on installing a CentOS beside of it, allowing her to select the OS at boot-time. Other system/OS installing options are not retained, please avoid ;-). My first attempt was to install the CentOS7 GNOME-Live on a USB flashdisk and to boot it on the machine. It was either freezing at grub stage

Hi all, I'm testing new "minimal" kickstarts files for CentOS6 and CentOS7. The CentOS6 kickstart works fine, but i've a dependency problem with the CentOS7 equivalent. In my kickstarts, i use network install with following repos/packages (for the repo, the only change is version number 6 <-> 7): url --url="http://mirror.in2p3.fr/ftp/linux/CentOS/7/os/x86_64/"

The Installer in CentOS7 is confusing, particularly the partitioning section, but it *does* let you do

hi, i'm evaluating performance of centos7 i did tests on centos6 x86_64/distro kernel 2.6.32, asterisk 11.16.0 with 500calls (7sec alaw, simple dialplan, pass trough - sipp generators/asterisk receiver with answer/playback) scenario - sipp generators - asterisk - asterisk receiver (i wrote ansible scenario for this if you are interested) then i reinstalled system to centos7 x86_64/distro

Thanks all for your answers ans suggestions. It cannot be a fail2ban problem as firewall was disabled on the server for the tests. The time was playing against me so I went back to centos6 (these desktops must be available monday) and all run fine. I will investigate this later. It's easy for me to switch from Centos6 to Centos7 as the OS is automatically installed (PXE boot + Kickstart)

Hi all, I write about libvirt inconsistent behavior when mixing io=native and cache=writeback. This post can be regarded as an extension, or clarification request, of BZ 1086704 (https://bugzilla.redhat.com/show_bug.cgi?id=1086704) On a fully upgraded CentOS6 x86-64 machine, starting a guest with io=native and cache=writeback is permitted: no errors are raised and the VM (qemu, really)

Still in the process of migrating from an old CentOS5 server to a brand new CentOS7. After finally getting Virtualbox-5.0 installed and a new Wondoze10 Pro installed it became time to shift the data from the old server to the new. The old server is headless and I installed the old WindozeXP into the Virtualbox4.x via the command line. To do some of the admin I needed to attach to the windoze

Hi All, I am switching from Fedora20 to CentOS7 since I now run all my Linux development in a VM and I get a more robust feature set (i.e. shared folders with the host that "just work", etc) The only issue I have thus far is VPN connections. Looking at what's installed on my old Fedora install I suspect I need these packages: kde-plasma-nm-vpnc kde-plasma-nm-openvpn

Hi all, Looking to move from VMware to Xen4CentOS. We currently run Centos7 as our servers main distort. All the documentation I?ve found on the Xen4CentOS only refers to Centos6. Do any of you know if it currently or is being developed to work with Centos7? thanks in advance

Hi, I have two processes spinning up independent sets of guests, letting the guests run for a while, and tearing them down. The two processes are generally giving their set of guests a different "run-period", so the guest spin-up/tear-down will happen during different cycles/phases. Call these processes A and B, each is currently managing 32 guests. I am seeing an issue, where when

Hello Everyone, We have centos6 server. And we are planning to upgrade it to Centos7.And GRUB 2 needs a new bios grub partition. Creating a new partition is too much risky. I am wondering if it is possible to replace Grub2 with Grub legacy on Centos7 machine? Thanks!! Sachin

Hi all. I'm trying to bring an Amazon VM into the LAN by following this guide [0]. However, it appears that OpenSSH on either RHEL7 or CentOS7 is broken as it is not creating tap interface but tun interface. I've tried this on both CentOS5 and CentOS6 and they both work as advertised! Downgrading the OS is not an option! CentOS5/6 gives me: ****************** tap1:
