The KVM disks are not guaranteed stable naming across reboots, so it is recommended to use /dev/disk/by-

{path|id|uuid|label} for the storage pool.

After creating the storage pool, when creating a volume based on the pool it requires a friendly naming convention like sda1.

To reproduce the issue:

1) Create a storage pool type 'disk'
2) Create a volume `virsh vol-create-as <pool_name> <volume_name> <size>`
3) Reboot the KVM host until the friendly name is no longer the same as /dev/disk/by-{path|id|uuid|label}

4) The volume path dose not change to line up with the storage pool

It looks like libvirt is using parted to get the names: `parted /dev/sda p`
