We can use the following commands for this:

# cd /var/lib/libvirt/images/
# qemu-img create -f raw dummy 100M

6. Next we will attach the created image to VPS.

To attach the created image on Centos 7 node, run the following command:

# virsh attach-disk kvmID /var/lib/libvirt/images/dummy hdb --cache none --targetbus virtio
