KVM

You can deploy the Sophos Firewall virtual appliance on the KVM (Kernel-based Virtual Machine) platform.

Prerequisites

  • You must have a server with x86 architecture with a recent Linux kernel and one of these processors:
    • Intel processor with VT (virtualization technology) extensions
    • AMD processor with SVM extensions (AMD-V)
  • Check if the CPU supports Intel VT or AMD-V, using these commands:
    • Intel VT: #!sh grep --color vmx /proc/cpuinfo
    • AMD-V: #!sh grep --color svm /proc/cpuinfo
  • Install the virt-manager (Virtual Machine Manager) application on a management device to manage the KVM. For details, go to KVM FAQs.
Hardware Specification
vCPU 1
vRAM 4 GB minimum
vNIC 2
Primary disk 16 GB minimum
Report disk 80 GB minimum

If you don't meet the minimum requirements for new installations of SFOS 18.0, or if you're migrating from an earlier version, Sophos Firewall goes into fail-safe mode.

Caution

Configure the vCPU and vRAM based on the purchased license. Don't exceed the maximum number of vCPUs specified in the license.
