KVM: Kernel-based Virtual Machine.

My Setup:

• RHEL9 Machine spinning on vbox.

• Preq: RHEL or any OS iso for server installation.

Steps to install KVM on RHEL:

1. Run below command to check if virtualization is enabled on your system:
   egrep -c '(vmx|svm)' /proc/cpuinfo

The output should be a number greater than 0. If not, enable virtualization in the BIOS settings of your system.

If you are using VBox, then check this box:

1. Install below packges from yum/dnf repo.

   sudo yum install virt-install virt-viewer libvirt virt-top libguestfs-tools xorg* -y

   

   After successful installation run following command: virt-manager to launch GUI.

   Note: Try opening the server in a new terminal if you are receiving the error below:

   (virt-manager:5994): Gtk-WARNING **: cannot open display:

2. Create VM using virt-manager GUI:

   • open virt-manager

     

• click on File > New Virtual Machine

• This will launch a fresh VM creation wizard. Since we had downloaded RHEL 9.0 from this page, we'll go with option 1.

  Select Local installation media > click Forward button.

  

  • Browse the download directory.

    

  • after that click Browse Local to find the ISO on the local path.

    

  • Select the iso & click open.

    

  • After choosing ISO, press Forward to go to the following stage.

    

  • Set Desired RAM and vCPUS for your Machine.

    

  • Set Desired Disk Size.

    

  • Select default Network in our Case.
    Note : We can create a bridge network too and select it at this point.

    

  • If all goes well you will have GRUB screen in front of you and you can proceed with linux installation.

    

    • Voilà!
