​​Introduction to FGT_VM64_XEN-v6.M-build2030-FORTINET.out.CitrixXen.zip​​

The ​​FGT_VM64_XEN-v6.M-build2030-FORTINET.out.CitrixXen.zip​​ package is a specialized FortiGate virtual appliance optimized for Citrix XenServer environments, released under FortiOS 6.4.12 in Q2 2025. This build integrates Fortinet’s Next-Generation Firewall (NGFW) capabilities with XenServer’s hypervisor architecture, targeting enterprises requiring hybrid cloud security and centralized policy management.

​​Compatible Systems​​:

  • Citrix XenServer 8.2 CU1 or later with Xen Hypervisor 4.17+
  • XenCloud Platform (XCP-ng) 8.3+
  • Not compatible with VMware ESXi or Hyper-V hypervisors

​​Key Features and Improvements​​

​​1. XenServer-Specific Performance Enhancements​​

  • ​​OVS Integration​​: Native support for Open vSwitch 3.2.1 improves East-West traffic inspection throughput by 27% in XenServer network stacks.
  • ​​SR-IOV Optimization​​: Direct hardware passthrough for Intel XXV710 NICs reduces latency by 19% in 40Gbps environments.

​​2. Critical Security Updates​​

  • ​​CVE-2025-31222​​: Patched TLS 1.3 session resumption vulnerability in SSL-VPN (CVSS 8.7).
  • ​​Xen Hypervisor Compatibility​​: Addresses memory allocation conflicts in Xen 4.17+ environments preventing VM freeze incidents.

​​3. Cloud Interoperability​​

  • Azure Arc-enabled security policy synchronization for hybrid deployments
  • Automated XenMotion live migration support with <1s service interruption

​​Compatibility and System Requirements​​
