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: grep --color vmx /proc/cpuinfo
    • AMD-V: 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.
