Introduction to FGT_VM64_XEN-v6-build0302-FORTINET.out.CitrixXen.zip Software
The FGT_VM64_XEN-v6-build0302-FORTINET.out.CitrixXen.zip package provides a pre-configured FortiGate virtual machine image optimized for Citrix XenServer hypervisors. This build specifically enhances security posture in virtualized environments by integrating FortiOS 6.0.6 with XenServer’s native virtualization capabilities.
Designed for cloud service providers and enterprises running Xen-based infrastructure, this virtual appliance supports FortiGate VM64-XEN deployments requiring 10Gbps+ threat protection throughput. The release addresses hypervisor-specific performance bottlenecks observed in earlier FortiOS 5.6.x versions, particularly in vNIC packet processing and storage I/O prioritization.
According to Fortinet’s virtualization compatibility matrix, build 0302 was officially released on March 25, 2025 as part of the Extended Support Program for virtual firewall deployments. It maintains backward compatibility with XenServer 8.2+ environments while introducing XenMotion live migration support.
