Troubleshooting

VNX relies mainly on KVM and libvirt, so it is important to check that both are working correctly in your system. To do that:

  • Processor with virtualization support. Check that your processor has support for virtualization extensions with the following command:
  • egrep '(vmx|svm)' --color=always /proc/cpuinfo
    

    If you see the word vmx (for Intel processors) or svm (for AMD processors) in red, your processor has virtualization support. Be aware that virtualization extensions are controled from the BIOS and maybe in your computer are disabled.

  • Check that KVM modules can be loaded with:
  •  modprobe kvm
     modprobe kvm_intel    # for Intel processors
     modprobe kvm_amd      # for AMD processors
