+= Setting resource quota limits for virtual machines
+
+Resource quotas that only use requests automatically work with virtual machines (VMs). If your resource quota uses limits, you must manually set resource limits on VMs. Resource limits must be at least 100 MiB larger than resource requests.
+
+.Procedure
+
+. Set limits for a VM by editing the `VirtualMachine` manifest. For example:
++
+[source,yaml]
+----
+apiVersion: kubevirt.io/v1
+kind: VirtualMachine
+metadata:
+  name: with-limits
+spec:
+  running: false
+  template:
+    spec:
+      domain:
+# ...
+        resources:
+          requests:
+            memory: 128Mi
+          limits:
+            memory: 256Mi  <1>
+----
+<1> This configuration is supported because the `limits.memory` value is at least `100Mi` larger than the `requests.memory` value.
+
+. Save the `VirtualMachine` manifest.
