How do i display storage pool information using kvm virsh?

The storage pool is a area of storage used for VM's. VM's use volumes within the storage pools.

# virsh pool-list
 Name                 State      Autostart 
-------------------------------------------
 default              active     yes       
 Pool0                active     yes

The default is the local disk. The Pool0 is another dedicated local disk storage pool, could be NFS, iSCSI, SAN, etc

To show more information on a storage pool.

# virsh pool-info default
Name:           default
UUID:           a8eac234-115f-734e-81aa-1d9b178683de
State:          running
Persistent:     yes
Autostart:      yes
Capacity:       20.97 GiB
Allocation:     6.40 GiB
Available:      14.56 GiB

To display the information on the volumes. This is using a local disk storage pool, called Pool0.

# virsh vol-list Pool0
 Name                 Path
