问题


Maybe this a newbie question, I am installing minikube. When I try to start minikube (minikube start --vm-driver hyperv --hyperv-virtual-switch "MiniKube" --alsologtostderr -v=8 --memory=2000) I see an error message in the log (panic: runtime error: index out of range [0] with length 0):

This is the complete log:

The issues you are encountering are strictly connected with this line:

minikube v1.9.2 en Microsoft Windows 10 Home Single Language 10.0.18362 Build 18362

Windows 10 Home does not support Hyper-V.

Citing official Microsoft page:

Enable Hyper-V to create virtual machines on Windows 10.
Hyper-V can be enabled in many ways including using the Windows 10 control panel, PowerShell or using the Deployment Imaging Servicing and Management tool (DISM). This documents walks through each option.

Note: Hyper-V is built into Windows as an optional feature -- there is no Hyper-V download.

Check Requirements

  • Windows 10 Enterprise, Pro, or Education
  • 64-bit Processor with Second Level Address Translation (SLAT).
  • CPU support for VM Monitor Mode Extension (VT-c on Intel CPUs).
  • Minimum of 4 GB memory.

-- Docs.microsoft.com: Virtualization: Enable hyper v

As you can see there is a requirement that forbids using Hyper-V with Windows 10 Home.

For your minikube to work you can either:

  • Use a different Hypervisor like for example Virtualbox and then start minikube start --vm-driver=virtualbox
  • Upgrade your Windows 10 to version that officially supports Hyper-V
