Before you deploy a new virtual machine, you can choose to configure the virtual hardware. When you create a virtual machine, the virtual disk is selected by default. You can use the New device drop-down menu on the Customize Hardware page to add a new hard disk, select an existing disk, or add an RDM disk.
For information about virtual disk configuration, including instructions for adding different types of disks, see Add a Hard Disk to a Virtual Machine.
For help configuring other virtual machine hardware, see Configuring Virtual Machine Hardware.
