## Create a new virtual machine using an ISO file from the content library
1. In the vSphere Client, click on the menu icon with the three horizontal lines in the top left of the menu bar.
2. Click on **Inventory**.
3. Select your vSphere cluster.

The new virtual machine is created.
## Troubleshooting
The creation of a VM may fail if the ISO content library is still downloading or synchronising the ISO image at the time of creation. If the creation of your VM fails, cancel the process and check whether the library is synchronised. To do this, click on Recent Tasks in the menu bar at the bottom and then on the arrow pointing upwards.
Wait until the synchronisation is displayed as completed in the task window. Then repeat the creation of the VM.
