Manage Instances

This section helps to get an understanding of managing instances.

Prerequisites

The following prerequisites must be met to manage your instances:

• The Virtual Scanner option must be turned on for your account.
  Contact Qualys Support or your Technical Account Manager if you want us to turn on this option.
• You must be a Manager or sub-user with permission to access and manage virtual scanner appliances.
  This permission may be granted to Unit Managers or your subscription may be configured to allow it to be granted to Scanners.

Instance Size

The recommended minimum instance configuration for the Scanner VM is 4 CPU cores and 8 GB of RAM. In the event of scan delays, failures, or performance issues, it is advisable to increase the instance size.

Ensure that the CPU: RAM ratio is maintained at 1:2 or 1:3 for optimal performance

Instance Snapshots/Cloning Not Allowed

Using a snapshot or clone of a virtual scanner instance to create a new instance is strictly prohibited. The new instance does not function as a scanner, and all configuration settings and platform registration information may be lost. This could also lead to scan failures and errors for the original scanner.

Moving/Exporting Instance Not Allowed

Moving or exporting a registered scanner instance from a virtualization platform (HyperV, VMware, XenServer) in any file format to a cloud platform (AWS, Azure, GCE, OpenStack) is strictly prohibited. Doing so breaks scanner functionality and permanently loses all of its settings.
