    Minimum System Memory Requirement for the Panorama Virtual Appliance
    Palo Alto Networks has increased the recommended Panorama virtual appliance memory requirement to a minimum of 64GB, up from 32GB. This impacts Panorama virtual appliances in Panorama and Log Collector mode to avoid any logging, management, and operational performance issues related to an under-provisioned Panorama virtual appliance.
    For new Panorama virtual appliance deployments, Palo Alto Networks recommends deploying the virtual machine with a minimum of 64GB. For existing Panroama virtual appliance deployments, See Increase the CPUs and Memory of the Panorama Virtual Appliance to increase the memory for an existing Panorama virtual appliance after successful upgrade to PAN-OS 11.0.
