+==== Helpful notes from a user group ====
+I didn't realise snapshotting virtual machines on unRAID was so easy with SSH.
+After spending too much time over the weekend testing GUI options for KVM management with unRAID and being disappointed, I learnt that it's super easy using SSH if you have configured your VM correctly.
+Configuration
+Machine: Q35-6.2
+BIOS: SeaBIOS (OVMF cannot create snapshots when the VM is running.)
+Primary vDisk Type: qcow2
+Commands
+List Virtual Machines
+virsh list --all
+List Snapshots
+virsh snapshot-list <vm-name>
+Create Snapshot
+virsh snapshot-create <vm-name>
+Create Snapshot With Name
+virsh snapshot-create-as <vm-name> --name <snapshot-name>
+Shutdown Virtual Machine
+virsh shutdown <vm-name>
+Shutting down the virtual machine before snapshotting is recommended, but not required.
+Revert Snapshot
+virsh snapshot-revert <vm-name> <snapshot-name>
+Delete Snapshot
+virsh snapshot-delete <vm-name> <snapshot-name>
+You must delete all snapshots before removing the VM through unRAID as it throws an error and wont let you delete the VM.
+Snapshot Info
+virsh snapshot-info <vm-name> <snapshot-name>
+==== Monitoring Unraid with Prometheus and Grafana ====
+Reference [[https://www.godwin.org/dokuwiki/lib/exe/fetch.php?media=monitoring_unraid_with_prometheus_and_grafana.pdf|this pdf file]] (the information will be integrated into this page in the future)
+==== Add Ubuntu Systems to Prometheus/Grafana Monitoring ====
+On each system where monitoring is desired, install the Prometheus Node Exporter:
+  sudo apt update
+  sudo apt install prometheus-node-exporter -y
+Verify it is running:
+  sudo systemctl status prometheus-node-exporter
+Test the metrics (optional):
+  curl http://localhost:9100/metrics
+Update the scrape_configs section in /mnt/user/appdata/prometheus/etc/prometheus.yaml:
+  scrape_configs:
+    - job_name: 'node'
+      static_configs:
+        - targets: ["localhost:9090"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+        - targets: ["192.168.1.xxx:9100"]
+Restart Prometheus
