virsh pool storage basics

Question

How or where were these pools created? Where are configuration files?

$ virsh pool-list --all
 Name                 State      Autostart 
-------------------------------------------
 default              active     yes       
 Downloads            active     yes       


$ virsh pool-info Downloads
Name:           Downloads
UUID:           fdbe7407-67c4-405d-8e46-9c2695a8b353
State:          running
Persistent:     yes
Autostart:      yes
Capacity:       219.88 GiB
Allocation:     34.87 GiB
Available:      185.01 GiB


$ virsh pool-info default
Name:           default
UUID:           cb72b02e-b436-4ec9-9460-d297744c4c69
State:          running
Persistent:     yes
Autostart:      yes
Capacity:       219.88 GiB
Allocation:     34.95 GiB
Available:      184.93 GiB

I believe that the pools were created by the virt-manager GUI.

Is there free space on default? I think that the Downloads pool is probably superfluous.

Here they are:

$ ll /etc/libvirt/storage
total 20
drwxr-xr-x 3 root root 4096 Nov 14 00:39 ./
drwxr-xr-x 7 root root 4096 Nov 12 14:22 ../
drwxr-xr-x 2 root root 4096 Nov 14 00:39 autostart/
-rw------- 1 root root  538 Nov 12 14:22 default.xml
-rw------- 1 root root  541 Nov 14 00:39 Downloads.xml

actual files:

$ sudo cat /etc/libvirt/storage/default.xml
