+# Is nested virtualization supported on Pouta?
+
+No, for the time being nested virtualization is not enabled in Pouta. Nested virtualization disables live migrations, and at this moment we consider that Live migration is a much more useful feature for our user than nested virtualization.
+
+!!! Info "Nested virtualization"
+    Nested virtualization is a feature that allows you to run virtual machines (VMs) inside other VMs. This is useful for testing and development purposes
+
+!!! Info "Live migration"
+    Live migration is the process of moving a running virtual machine between different physical machines without rebooting or shuting down the virtual machine. There might be a short downtime during the migration, but the processes running on the virtual machine do not perceive this downtime.
