Resource Configuration

Following is the list of requirements for configuring resources.

Minimum Resource Configuration:

4 x vCPU | 8 GB RAM* | 1 x 56GB virtual HDD

Maximum Resource Configuration:

16 x vCPU (recommended maximum of 8) | 16GB RAM*

* Reserved RAM If your hypervisor supports it, Qualys strongly recommends that any RAM allocated to the Qualys Scanner Appliance also be reserved. For example, if you allocate 8GB of RAM to the Qualys Scanner Appliance virtual machine, you should also reserve a full 8GB of RAM for the virtual machine. Failure to do so can result in excessive memory paging by the hypervisor, resulting in decreased scanner performance and responsiveness and even a system failure if the hypervisor is thrashing badly.

Networking Configurations

General

Up to 2 x vNICs (virtual network interfaces)
- One interface in use
  Interface 1: LAN/WAN interface - used for both scanning of targets and outbound connection to the Qualys Cloud Platform
- Two interfaces in use
  - Interface 1: LAN interface - used for scanning of targets
  - Interface 2: WAN interface - used for outbound connection to the Qualys Cloud Platform
    
    LAN and WAN must be on different subnets.
IPv4 address assignment: static, DHCP
IPv6 address assignment (LAN interface only): autoconfiguration, static
Proxy server - outbound to Qualys Cloud Platform
username/password authentication supported
VLAN tagging
Static routing
Supported network adapter types on ESXi servers include E1000, VMXNET2 (Enhanced) and VMXNET3
