+== Virtualization ==
+Virtual machines are KVM guests managed with libvirt.
+=== Storage ===
+All virtual disks come from a pool backed by the main LVM VG:
+  virsh # pool-define-as nvme-pool logical --source-name nvme-pool
+  Pool nvme-pool defined
+  virsh # pool-start nvme-pool
+  Pool nvme-pool started
+  virsh # pool-autostart nvme-pool
+  Pool nvme-pool marked as autostarted
+  virsh # pool-info nvme-pool
+  Name:           nvme-pool
+  UUID:           5812819f-b8bf-484e-98fb-2e100fe83df2
+  State:          running
+  Persistent:     yes
+  Autostart:      yes
+  Capacity:       1.64 TiB
+  Allocation:     250.00 GiB
+  Available:      1.40 TiB
+Disks assigned to VMs will appear here:
+ virsh # vol-list nvme-pool
+  Name         Path
+ -----------------------------------------
+  aslo1-root   /dev/nvme-pool/aslo1-root
+  aslo1-srv    /dev/nvme-pool/aslo1-srv
+  backup       /dev/nvme-pool/backup
+Disks can be created, listed and deleted using the vol-* commands:
+  virsh # vol-create-as nvme-pool testvm-root 20G
+  Vol testvm-root created
+  virsh # vol-info testvm-root --pool nvme-pool
+  Name:           testvm-root
+  Type:           block
+  Capacity:       20.00 GiB
+  Allocation:     20.00 GiB
+  virsh # vol-delete testvm-root --pool nvme-pool
+  Vol testvm-root deleted
+'''NOTE''': avoid allocating large VM volumes as image file within the host's root filesystem, as they're slow and hard to manage. It's ok to use images for test VMs.
