 Cisco Nexus9000v virtualized router is identified with `[[[ kind_code_name ]]]` kind in the [topology file](../topo-def-file.md). It is built using [vrnetlab](../vrnetlab.md) project and essentially is a Qemu VM packaged in a docker container format.
 
 Cisco Nexus 9000v nodes launched with containerlab comes up pre-provisioned with SSH, SNMP, NETCONF, NXAPI and gRPC services enabled.

-    Containers with Nexus 9000v inside will take ~8-10min to fully boot.  
-    You can monitor the progress with `docker logs -f <container-name>`.

-Cisco Nexus 9000v node launched with containerlab can be managed via the following interfaces:
-
-=== "bash"
-    to connect to a `bash` shell of a running Cisco Nexus 9000v container:
-    ```bash
-    docker exec -it <container-name/id> bash

+/// details | N9kv Lite
+If you have a Nexus 9000v Lightweight variant, you can use the same `[[[ kind_code_name ]]]` to launch it
+
+By default, Nexus 9kv image with require 10GB memory and 4 CPU. However `n9kv-lite` VM requires less resources, so you would want to tune the defaults down.
+
+Following is sample for setting up lower memory and CPU for the `n9kv-lite`:
+
+```yaml
+topology:
+  nodes:
+    node:
+      kind: [[[ kind_code_name ]]]
+      env:
+        QEMU_MEMORY: 6144 # N9kv-lite requires minimum 6GB memory
+        QEMU_SMP: 2 # N9kv-lite requires minimum 2 CPUs
+```
+
+Please refer to ['tuning qemu parameters'](../vrnetlab.md#tuning-qemu-parameters) section for more details.
