HOW TO INSTALL OVENVZ ON CENTOS - STEP 2

The installation process should automatically update the GRUB bootloader settings. Make sure the new settings have been added, go to the bootloader settings with your favorite text editor (I use nano),

nano /boot/grub/menu.lst

 for example, setting the GRUB bootloader her as follows:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /boot/, eg.
#          root (hd0,0)
#          kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
#          initrd /initrd-version.img
#boot=/dev/sda
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
hiddenmenu
title CentOS OpenVZ (2.6.18-53.1.19.el5.028stab053.14)
root (hd0,0)
kernel /vmlinuz-2.6.18-53.1.19.el5.028stab053.14 ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.18-53.1.19.el5.028stab053.14.img
title CentOS (2.6.18-92.1.1.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-92.1.1.el5 ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.18-92.1.1.el5.img
title CentOS (2.6.18-92.el5)
root (hd0,0)
kernel /vmlinuz-2.6.18-92.el5 ro root=/dev/VolGroup00/LogVol00
initrd /initrd-2.6.18-92.el5.img

 Next install some additional tools for OpenVZ users

yum install vzctl vzquota

 Open /etc/sysctl.conf

nano /etc/sysctl.conf

 make sure the settings as follows:

[…]
net.ipv4.ip_forward = 1
net.ipv4.conf.default.proxy_arp = 0
net.ipv4.conf.all.rp_filter = 1
kernel.sysrq = 1
net.ipv4.conf.default.send_redirects = 1
net.ipv4.conf.all.send_redirects = 0
net.ipv4.icmp_echo_ignore_broadcasts=1
net.ipv4.conf.default.forwarding=1
[…]

 To change the sysctl settings, use the command
