Introduction to “Cisco_Secure_FW_Mgmt_Center_Virtual300_KVM-7.3.1-19.qcow2”
This KVM-optimized qcow2 image enables deployment of Cisco Secure Firewall Management Center Virtual 300 (FMCv300) on Linux hosts using QEMU/KVM virtualization. Designed for enterprises managing large-scale firewall deployments, this 7.3.1 maintenance release enhances scalability to support centralized control of up to 300 Firepower Threat Defense (FTD) devices across hybrid environments.
As part of the 7.3.x release train certified for Red Hat Enterprise Linux 8.4+ and Ubuntu 20.04 LTS, this build specifically addresses memory management challenges in multi-tenant configurations while maintaining backward compatibility with FTD 7.0+ device policies. The Virtual300 designation indicates enhanced resource allocation for organizations requiring concurrent management of physical firewalls, cloud-native instances, and virtual security appliances.
