Step 1: Unzip the downloaded VMware appliance file

Unzip the downloaded VMware appliance file to a folder of your choice. The archive contains a subfolder. For example the Vmware appliance with UCS contains the following files in the subfolder “UCS-Demo-Image”:

  • UCS-Demo-Image.vmdk
  • UCS-Demo-Image.vmxf
  • UCS-Demo-Image.vmx
  • UCS-Demo-Image.vmsd

Step 2: Import the VM image

Import the VM image by selecting the downloaded file and start the import.

1. Click on “Open a Virtual Machine”, select the subfolder of the extracted files, and open the UCS-Demo-Image.vmx file.

2. Click on “Power On” to start the virtual machine and run the pre-installed UCS system.

Note for users of Linux Desktops: VMware Workstation Player version 14.1 has a bug opening the virtual machine. Please follow the instructions in the Univention Forum.
