=== What you learned

In this exercise, you learned that virtual machines running on OpenShift Virtualization operate similarly to pods.
Specifically, when configuring resource `requests` for CPU or memory, you cannot allocate more resources to a virtual machine than are available on a single node.

=== What you learned

In this exercise, you learned how to troubleshoot issues preventing external access to an application by examining all related network components in OpenShift.
You tested the application within the virtual machine, verified the service, and checked the route.
These steps help you to determine whether the issue is within OpenShift or an external system.
