Deploying VMs using the thin provisioning method

Perform the following steps to get started with VM deployment using the thin provisioning method:

  1. Create two new qcow2 images using /vms/win7.raw as the backing file:
    # qemu-img create -b /vms/win7.img -f qcow2 /vms/vm1.qcow2
    #qemu-img create -b /vms/win7.img -f qcow2 /vms/vm2.qcow2
    
  2. Verify that the backing file attribute for newly created qcow2 images is pointing correctly to the image /vms/win7.raw, using the qemu-img command:
    qemu-img info /vms/vm2.qcow2
    image: /vms/vm2.qcow2
    file format: qcow2
    virtual size: 10G (10737418240 bytes)
    disk size: 196K
    cluster_size: 65536
    backing file: /vms/win7.img
    Format specific information:
      compat: 1.1
      lazy refcounts: false
      refcount bits: 16
      corrupt: false
