13.1. Creating Volumes
This section shows how to create disk volumes inside a block based storage pool. In the example below, the
virsh vol-create-as command will create a storage volume with a specific size in GB within the guest_images_disk storage pool. As this command is repeated per volume needed, three volumes are created as shown in the example.
# virsh vol-create-as guest_images_disk volume1 8G
Vol volume1 created
# virsh vol-create-as guest_images_disk volume2 8G
Vol volume2 created
# virsh vol-create-as guest_images_disk volume3 8G
Vol volume3 created
# virsh vol-list guest_images_disk
