Virtual systems are supported on PA-400 Series (PA-440, PA-450, and PA-460 only), PA-1400 Series,
PA-3200 Series, PA-3400 Series, PA-5200 Series, PA-5400 Series, and PA-7000 Series
firewalls. Each firewall series supports a base number of virtual systems; the number
varies by platform. A Virtual Systems license is required to support multiple virtual
systems on PA-400 Series, PA-1400 Series, PA-3200 Series, and PA-3400 Series firewalls,
and to create more than the base number of virtual systems supported on a platform.
You can
limit the resource
allocations for sessions, rules and VPN tunnels allowed for
a virtual system, and thereby control firewall resources. Each resource
setting displays the valid range of values, which
varies per firewall model. The
default setting is 0, which means the limit for the virtual system is
the limit for the firewall model. However, the limit for a specific
setting isn’t replicated for each virtual system. For example, if
a firewall has four virtual systems, each virtual system can’t have
the total number of Decryption Rules allowed per firewall. After
the total number of Decryption Rules for all of the virtual systems
reaches the firewall limit, you cannot add more.
