 virt-manager is already installed in above steps. But to create and manage VMs using virt-manager the current user should be a member of the libvirt and kvm user groups. So let us add the Ubuntu user to the above groups.

-== Create and Manager VMs using Virtual Machine ==
+The virt-manager window will be opened. To create a new VM please click on the icon on the left most side.
+
+Now VM wizard will appear. Select the option Local Install media (ISO image or CDROM) to install the guest with a ISO image.
+
+Next click on Browse button to select an ISO image. 
+
+In next window click Browse Local.
+
+And go to the Downloads directory. There should be OS image called linux-lite-6.2-64bit.iso. This is a linux distribution based on Ubuntu. Select it and open.
+
+Since Linux Lite is not an very common operating system it will not be automatically detected. So uncheck the checkbox at the bottom of the window as below. Then type Generic default in the above text box. Then select Forward button to go to the next step.
+
+Now you have to specify Memory and number of virtual CPUs for the VM. For this linux distribution minimum of 768MB RAM is required. 1 number of CPU will be good enough. Once given click Forward button.
+
+In this window you can specify an hard disk size. For this linux distribution minimum of 8GB storage size is required. Once done select Forward button.
+
+Now you have specify the Name of the VM to be created.  You can also unfold the Network Selection to see available network interfaces. Here we will choose bridge interface br0 that we created earlier. Once everything looks good click on Finish to create the VM.
+
+Next comes is the Guest operating system installion Wizard. This shouldn't be new to you. You can either choose to install the operating system on the created VM or choose to boot from the live system inside the ISO image. If you select the first option we can use the operating system without installing in the VM.

+== Create and Manage VMs using Virtual Machine ==
 
 The virt-install command-line tool is used for creating virtual machines on the terminal. A number of parameters are required when creating a virtual machine.
