1. Install the following packages for setting up guest hosts using KVM virtualization . # yum install virt-install virsh libvirt kvm # yum install kvm python-virtinst libvirt libvirt-python virt-manager # yum install virt-viewer libguestfs-tools 2. Check whether the following modules are loaded . If not , load it manually using insmod. # modinfo kvmfilename: /lib/modules/2.6.32-220.el6.x86_64/kernel/arch/x86/kvm/kvm.kolicense: GPLauthor: Qumranetsrcversion: E0EC656A576974AAE72808Ddepends:vermagic: 2.6.32-220.el6.x86_64 SMP mod_unload modversionsparm: oos_shadow:boolparm: ignore_msrs:boolparm: allow_unsafe_assigned_interrupts:Enable device assignment on platforms without interrupt remapping support.

Restart libvirtd service # /etc/init.d/libvirtd restart Stopping libvirtd daemon: [FAILED] Starting libvirtd daemon: Setting Up Networking 1. Create a new br0 network device of TYPE Bridge using system-config-network command or create it manually as shown below. Assign IP Address and other network configuration details based on your requirement. . # vim /etc/sysconfig/network-scripts/ifcfg-br0 DEVICE="br0" NM_CONTROLLED="no" ONBOOT=yes TYPE=Bridge BOOTPROTO=none IPADDR=192.168.2.148 PREFIX=26 GATEWAY=192.168.2.130 NAME="System br0" 2. Modify the original network configuration file (e.g /etc/sysconfig/network-scripts/ifcfg-eth0 ) and comment out BOOTPROTO , IPADDR , PREFIX and GATEWAY parameters . Add the following network parameter and restart network service . BRIDGE=br0 So , the final eth0 network interface file will be as follows $ cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0 NM_CONTROLLED=no BRIDGE=br0 ONBOOT=yes TYPE=Ethernet #BOOTPROTO=static #IPADDR=192.168.2.148 #NETMASK=255.255.255.192 USERCTL=no #GATEWAY=192.168.2.130 3. Restart network service #/etc/init.d/network restart If all went fine your network configuration will be as follows: # ifconfig eth0 Link encap:Ethernet HWaddr 44:1E:A1:55:B0:B0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:724970 errors:0 dropped:0 overruns:0 frame:0 TX packets:8032 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:239225199 (228.1 MiB) TX bytes:1348488 (1.2 MiB) br0 Link encap:Ethernet HWaddr 44:1E:A1:55:B0:B0 inet addr:192.168.2.147 Bcast:192.168.2.191 Mask:255.255.255.192 inet6 addr: fe80::461e:a1ff:fe55:b0b0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:22 errors:0 dropped:0 overruns:0 frame:0 TX packets:30 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:3898 (3.8 KiB) TX bytes:3196 (3.1 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:2794116 errors:0 dropped:0 overruns:0 frame:0 TX packets:2794116 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:260264756 (248.2 MiB) TX bytes:260264756 (248.2 MiB) Creating the Guest Hosts There are two tools available for creating guest hosts . One is virt-manager tool which has a graphical interface and the other is virt-install tool which has a text interface . We will be using virt-install tool to setup guest hosts. For our case , we will be creating a virtual hosts with 3 GB of RAM , 3 no of CPUs and with a hard disk space of 20G . The command will be as follows: # virt-install --network bridge=br0 \ --name vm-dbase \ --ram=3072 \ --vcpus=3 \ --disk path=/var/lib/libvirt/p_w_picpaths/vm1-mysql.img,size=20 \ --graphics none \ --location=http://192.168.4.139/rhelisos \ --extra-args="console=tty0 console=ttyS0,115200" \ --os-type=linux \ --os-variant=rhel6 Little description is as follows: --vcpus= Number of virtual cpus to configure for the guest. --location=An HTTP server location containing an installable distribution p_w_picpath --disk=Specifies media to use as storage for the guest, with various options including size of disk --name=Name of the new guest virtual machine instance. Press Enter and here you go , creation of virtual host will get initiated . Follow the on-screen instructions for setting up the OS . These are the standard instructions we need to pass through while installing Linux . Once you are done providing all the parameters , a minimal OS installation will be done. The Guest host will be rebooted after installation is complete and you will be provided with a login prompt to login into the guest operating system .
