==Booting From a Volume== <!--T:22-->
==Booting From a Volume== <!--T:22-->
If you want to run a persistent machine (flavors starting with a 'p'), it is safest to boot from a volume. When you boot a VM from an image rather than a volume, the VM is stored on the local disk of the actual machine running the VM. If something goes wrong with that machine or its disk the VM may be lost. Volume storage has redundancy which protects the VM from hardware failure.
