+===== Harddisks =====
+It’s also possible to add a disk to a running VM. The disk can be a disk image or a LVM volume. It’s possible to resize the disk, but, you have to reboot the client or relaod the kernel disk table (''%%partx%%'', only CentOS >=7).
+  * Add (persistent) a disk to a VM:<code bash>
+virsh attach-disk ds --source /dev/sysvg/ds_test --target vdb --persistent
+</code> \\ This adds a new disk to the ''%%ds%%'' VM as ''%%/dev/vdb%%'' persistently.
+| **Note:**  | The disk is a logical volume on the KVM host  |
