Configure Virtual Systems
Creating a virtual system requires that you have the following:
A superuser administrative role. An interface configured. A Virtual Systems license if you are configuring a PA-2000 or PA-3000 Series firewall, or if you are creating more than the base number of virtual systems supported on the platform. See Platform Support and Licensing for Virtual Systems.
Configure a Virtual System
Enable virtual systems. Select Device > Setup > Management and edit the General Settings. Select the Multi Virtual System Capability check box and click OK. This action triggers a commit if you approve it. Only after enabling virtual systems will the Device tab display the Virtual Systems and Shared Gateways options.
Create a virtual system. Select Device > Virtual Systems, click Add and enter a virtual system ID, which is appended to “vsys” (range is 1-255). The default ID is 1, which makes the default virtual system vsys1. This default appears even on platforms that do not support multiple virtual systems. Check the Allow forwarding of decrypted content check box if you want to allow the firewall to forward decrypted content to an outside service. For example, you must enable this option for the firewall to be able to send decrypted content to WildFire for analysis. Enter a descriptive Name for the virtual system. A maximum of 31 alphanumeric, space, and underscore characters is allowed.
Assign interfaces to the virtual system. The virtual routers, vwires, or VLANs can either be configured already or you can configure them later, at which point you specify the virtual system associated with each. On the General tab, select a DNS Proxy object if you want to apply DNS proxy rules to the interface. In the Interfaces field, click Add to enter the interfaces or subinterfaces to assign to the virtual system. An interface can belong to only one virtual system. Do any of the following, based on the deployment type(s) you need in the virtual system: In the VLANs field, click Add to enter the VLAN(s) to assign to the vsys. In the Virtual Wires field, click Add to enter the virtual wire(s) to assign to the vsys. In the Virtual Routers field, click Add to enter the virtual router(s) to assign to the vsys. In the Visible Virtual System field, check all virtual systems that should be made visible to the virtual system being configured. This is required for virtual systems that need to communicate with each other. In a multi-tenancy scenario where strict administrative boundaries are required, no virtual systems would be checked. Click OK.
(Optional) Limit the resource allocations for sessions, rules, and VPN tunnels allowed for the virtual system. The flexibility of being able to allocate limits per virtual system allows you to effectively control firewall resources. On the Resource tab, optionally set limits for a virtual system. Each field displays the valid range of values; there are no default values. Sessions Limit If you use the show session meter CLI command, it displays the Maximum number of sessions allowed per dataplane, the Current number of sessions being used by the virtual system, and the Throttled number of sessions per virtual system. On a PA-7000 Series firewall, the Current number of sessions being used can be greater than the Maximum configured for Sessions Limit because there are multiple dataplanes per virtual system. The Session Limit you configure on a PA-7000 Series firewall is per dataplane, and will result in a higher maximum per virtual system.

Save the configuration. Click Commit and OK. The virtual system is now an object accessible from the Objects tab.
Create at least one virtual router for the virtual system in order to make the virtual system capable of networking functions, such as static and dynamic routing. Alternatively, your virtual system might use a VLAN or a virtual wire, depending on your deployment. Select Network > Virtual Routers and Add a virtual router by Name. For Interfaces, click Add and from the drop-down, select the interfaces that belong to the virtual router. Click OK.
Configure a security zone for each interface in the virtual system. For at least one interface, create a Layer 3 security zone. See Configure Interfaces and Zones.
Configure the security policy rules that allow or deny traffic to and from the zones in the virtual system. See Create a Security Policy Rule.
Save the configuration. Click Commit and OK. After creating a virtual system, you can use the CLI to commit a configuration for only a specific virtual system: commit partial vsys vsys<id>
(Optional) View the security policies configured for a virtual system. Open an SSH session to use the CLI. To view the security policies for a virtual system, in operational mode, use the following commands: set system setting target-vsys <vsys-id> show running security-policy
