The Microsoft SQL Server 2005 Express database package is installed and configured when you select Microsoft SQL Server 2005 Express as your database during VirtualCenter installation or upgrade. This is shown in
Installing VMware Infrastructure Management Software. No additional configuration is required.
If Microsoft SQL Server 2005 Express is already installed, review the required database patches specified in
Table 2-1. If you do not prepare your database correctly, the VirtualCenter installer might display error and warning messages.
