“Storage pools” are storage resources managed by a VM host. A storage pool is a given amount of storage set aside for use by VMs. A pool can be organized into storage volumes, assigned to VMs as individual block devices. More information is available for both libvirt and LXD storage pools.
[note] For the Beta version of LXD VM hosts, each VM can be assigned a single block device from the storage pool. [/note]
MAAS displays information about each VM host’s storage pools so you can understand your resource usage at a glance:
