How to use KVM cloud images on Ubuntu Linux

by

To use KVM cloud images on Ubuntu Linux, you need to have KVM virtualization software installed on your system. Here’s the step by step guide to use KVM cloud images:

  1. Install KVM and required utilities:

     
    $ sudo apt-get install qemu-kvm libvirt-bin virt-manager

  2. Download the cloud image:

    You can download cloud images from various cloud providers such as AWS, Google Cloud, etc. or from the official Ubuntu cloud images repository.

  3. Create a new virtual machine:

     
    $ virt-install --import --name vm-name --memory 2048 --vcpus 2 --disk path=/path/to/image.qcow2,format=qcow2 --network network=default

    The above command will create a new virtual machine with 2048 MB of memory, 2 virtual CPUs and the disk image file /path/to/image.qcow2 in qcow2 format.

  4. Start the virtual machine:

     
    $ virsh start vm-name

  5. Connect to the virtual machine:

    You can connect to the virtual machine using the virt-viewer tool:

     
    $ virt-viewer vm-name

Note: Replace vm-name with the desired name for your virtual machine. You may also need to adjust the other parameters, such as memory, vCPUs, and disk image path, to match your specific requirements.
