Virtual Analyzer does not contain any images by default. To analyze samples, you must prepare and import at least one image in the Open Virtual Appliance (OVA) format.
You can use existing VirtualBox or VMware images, or create new images using VirtualBox. For details, see Chapters 2 and 3 of the Virtual Analyzer Image Preparation User's Guide at http://docs.trendmicro.com/en-us/enterprise/virtual-analyzer-image-preparation.aspx.
Before importing, validate and configure images using the Virtual Analyzer Image Preparation Tool. For details, see Chapter 4 of the Virtual Analyzer Image Preparation User's Guide.
The hardware specifications of your product determine the number of images that you can import and the number of instances that you can deploy per image.
