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.
modprobe kvm modprobe kvm_intel # for Intel processors modprobe kvm_amd # for AMD processors
