AMD Graphic Driver (Radeon 6400 series) Troubleshoot

i have faced a problem with this graphic card.
whenever i update my kernel version in the CentOS-6_x86_64 then the graphic is not supported by the card and hang the system in command line and not give the further response to work.
The reason is the driver of the graphic card is work with kernel and whenever the kernel updated then the graphic driver is not combined with it.
So the solution is following for get back the Graphic:

  1. you can stick to kernel version on which you have install graphic driver.
  2. you can update the kernel and after that boot it in command line and install the graphic driver again on updated kernel.
I have done it three time when i updated my kernel.

you can do it in this way:-

1. choose the single mode with updated kernel and get the command line.
then install the driver again and reboot the system.
2. you can also do this by another way. In old kernel mode, first edit the file /etc/inittab for command line mode then reboot the system to get command line mode booted with updated kernel and install the graphic driver again in the system & reboot.

Step2: Now install AMD Graphic driver
#sh amd-driver-installer-12-4-x86.x86_64.run

Step3: check log file
#vim /usr/share/ati/fglrx-install.log

there will be an error like this

"ERROR: Module drm is in use by i915,drm_kms_helper"
.
.
"You must change your working directory to /lib/modules/fglrx
and then call ./make_install.sh in order to install the built module."

You can ignore these lines happily if they don’t contain any error message. You don’t really need to execute the command mentioned in those lines.

Step4: Blacklist radeon and radeonhd kernel modules

Add these lines to /etc/modprobe.d/blacklist.conf.

blacklist radeon

Port forward of KVM Guest Virtual Machine through Host Machine using IPTABLE/FIREWALL in Linux System

Port forward of KVM Guest Virtual Machine through Host Machine using IPTABLE/FIREWALL in Linux System
There is a lot of method given in Internet for KVM guest machine port forwarding but I always look for the simple solution that can work in any Linux System.

I have issue during the port forward by IPTABLE/FIREWALL as it disable the Internet access within KVM guest machine.
If I look for Internet access within KVM guest machine then system disable port forwarding.

I have implement the simple solution in CentOS 6.5 x86_64 with can work in both situation as follows:

Step 1: Restart libvirtd service, so that it will modify your firewall rules as per KVM requirement.
# service libvirtd restart
Step 2: You need to add two rules in IPTABLE for NAT and FILTER
# iptables-save > iptable_save_default_libvirtd
# cp iptable_save_default_libvirtd iptable_modifed_libvirtd
# vim  iptable_modifed_libvirtd

Add line after *nat for SSH access

Yum command for download list of packages

Some time we need the download the software but not to install.
Also we have a list of software from repository in a text file but need to download by the yum.
To solve this kind of problem we need some trick of Linux,
download the package yum-downloadonly plugin
create a text file with rpm name.
now parse it to yum command
#yum install $(cat rpm-list.txt)

to download only the packages
#yum install <package name> --downloadonly --downloaddir=/home/user/

combine command
# yum install  $(cat rpm-list.txt) --downloadonly --downloaddir=/home/user

create a list from yum.log
#cp /var/log/yum.log /home/user/yum.log

select the package name only
# awk '{print $5}' /home/user/yum.log > rpm-list.txt

view the list
# cat rpm-list.txt

 to query about a package
# repoquery --list <package name>

to take information about package
#yum info <package name>

to show the list of packages
# yum list

to find a package for yum list
# yum list | grep <package name>
