    • AMD processor with SVM extensions (AMD-V)

  • Check if the CPU supports Intel VT or AMD-V using the following 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.
