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.
Deep Discovery Web Inspector supports a maximum of three image groups at a time, and the maximum number of instances for Virtual Analyzer Images is 8 for model 510/1100 and 20 for model 4200.
