# 6, Creating VMs with pools .

  # First, Create a VM volume .
    $ virsh vol-create-as my_pool centos1.raw 10G --format raw            # raw, pool .
    $ virsh vol-create-as my_pool centos1.qcow2 10G --format qcow2        # qcow2, pool .
    $ virsh vol-info --pool my_pool centos1
    = [virsh] only, No [dd] or [qemu-img] .  


  # Then, Create the VM .
    $ virt-install \
      --name centos1 \
      --vcpus=1 \
      --ram=1024 \
      --network bridge:br0 \
      --disk "vol=my_pool/centos1.qcow2" \
      --graphics none \
      --location /home/zer0err0r/centos7.iso \
