Introduction to FGT_VM64_XEN-v6-build0200-FORTINET.out.CitrixXen.zip

This virtualization package (​​FGT_VM64_XEN-v6-build0200-FORTINET.out.CitrixXen.zip​​) delivers Fortinet’s flagship FortiGate-VM64 virtual firewall optimized for Citrix XenServer environments. Designed to secure hybrid cloud infrastructures, it integrates advanced threat protection with XenServer 6.5+ hypervisors, addressing 17 CVEs disclosed in FortiOS 6.0.x series. Compatible with XenServer 6.5/8.2 clusters and Citrix Hypervisor 8.2 CU1, this build enhances east-west traffic inspection while maintaining <5ms latency for high-frequency trading and financial workloads.


Key Features and Improvements

  1. ​Hypervisor-Optimized Security​​:

    • Mitigates ​​CVE-2025-32801​​ (CVSS 9.6), a heap overflow vulnerability in SSL-VPN services exposed in XenServer’s network stack.
    • Implements hardware-assisted SR-IOV passthrough for 40Gbps threat inspection on XenServer-certified NICs.
  2. ​Performance Benchmarks​​:

    • Achieves 12M concurrent sessions with 2 vCPUs/4GB RAM allocation – 30% improvement over FortiOS 6.0.15.
    • Reduces vSwitch packet processing latency by 22% through XenServer-specific memory optimizations.
  3. ​Cloud Integration​​:

    • Supports Citrix CloudPlatform 4.13 for automated security policy orchestration.
    • Enables live VM migration (XenMotion) with preserved IPSec VPN tunnel states.
  4. ​Management Enhancements​​:

    • Introduces XenCenter plugin v3.1 for unified firewall/VPN monitoring.
    • Fixes log export failures to FortiAnalyzer in multi-tenant XenServer deployments.
