VM host storage pools
"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.
For the Beta version of LXD VM hosts, each VM can be assigned a single block device from the storage pool.
MAAS displays information about each VM host’s storage pools so you can understand your resource usage at a glance:
