# Troubleshooting Virtual Session Creation on Linux
<a name="troubleshooting-linux-virtual-session-creation"></a>

If connecting to a virtual session results in a `No session available` or `The sessionId {{session}} is not available` error, this is probably due to the fact that the virtual session creation failed and was terminated. 

You can check if the session is present with the `dcv list-sessions` command. See [Viewing Amazon DCV sessions](managing-sessions-lifecycle-view.md) for more information about inspecting running sessions. If the session is not present in the list, then it might have failed.
