KVM Configuration

KVM Installation and configuration
1. Install the RHEL FOR 64Bit.
2. Create the Yum Server For RHEL 64Bit.
3. Now check the virtualization flag
[root@vijay ~]# egrep '(vmx|svm)' --color=always /proc/cpuinfo
4. To install KVM and virtinst (a tool to create virtual machines), we run
[root@vijay ~]# yum install kvm* qemu* libvirt* python-virtinst*
5. Then start the libvirt daemon:
[root@vijay ~]# /etc/init.d/libvirtd start
6. To check if KVM has successfully been installed, run
[root@vijay ~]# virsh -c qemu:///system list
It should display something like this:
Id Name
State
----------------------------------
7. To do this, we install the package bridge-utils...
[root@vijay ~]# yum install bridge-utils*
8. I disable NetworkManager and enable "normal" networking. NetworkManager is good
for desktops where network connections can change (e.g. LAN vs. WLAN), but on a server
you usually don't change network connections:
[root@vijay ~]# /etc/init.d/NetworkManager stop
[root@vijay ~]# chkconfig NetworkManager off
[root@vijay ~]# /etc/init.d/network restart
9. To configure the bridge, create the file /etc/sysconfig/network-scripts/ifcfg-br0 (please
use the BOOTPROTO, DNS1 (plus any other DNS settings, if any), GATEWAY, IPADDR,
NETMASK and SEARCH values from the /etc/sysconfig/network-scripts/ifcfg-eth0 file):
[root@vijay ~]# vim /etc/sysconfig/network-scripts/ifcfg-br0
################################################################
DEVICE=br0
TYPE=Bridge
VIJAY SINGH
BOOTPROTO=static
GATEWAY=192.168.0.1
IPADDR=192.168.0.100
NETMASK=255.255.255.0
ONBOOT=yes
################################################################
10. Modify /etc/sysconfig/network-scripts/ifcfg-eth0 as follows (comment out
BOOTPROTO, DNS1 (and all other DNS servers, if any), GATEWAY, IPADDR,
NETMASK, and SEARCH and add BRIDGE=br0):
[root@vijay ~]# vim /etc/sysconfig/network-script/ifcfg-eth0
##############################################################
DEVICE=eth0
#BOOTPROTO=none
#DNS1=145.253.2.75
#GATEWAY=192.168.0.1
HWADDR=00:1e:90:f3:f0:02
#IPADDR=192.168.0.100
#NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
IPV6INIT=no
USERCTL=no
BRIDGE=br0
##############################################################
11. Then reboot the system:
[root@vijay ~]# init 6
12. Now install the “virt-manager”
[root@vijay ~]# yum install virt-manager*
13. Now run the following command to start virtual machine.
[root@vijay ~]# virt-manager
And Install Your KVM VIRTUAL MACHINE
