Change settings of Hyper-V
This is to work around a bug of minikube.
Open Hyper-V and go to Actions -> Virtual Switch Manager
Click on New virtual network switch on the right hand side, select External for the network type, and then click the Create Virtual Switch button.
Name the network Minikube v switch and then set it as an external network
Run the following command in command prompt with admin privileges to start the minikube VM and configure it to be used with kubectl
C:\windows\system32>minikube start --vm-driver hyperv --hyperv-virtual-switch "minikube v switch"
o minikube v0.34.1 on windows (amd64)

Minikube had error so delete existing Minikube VM
The minikube delete command can be used to delete your cluster. This command shuts down and deletes the Minikube Virtual Machine. No data or state is preserved.
C:\windows\system32>minikube delete
- Powering off "minikube" via SSH ...
x Deleting "minikube" from hyperv ...
- The "minikube" cluster has been deleted.
Set the correct NIC
First create a vSwitch in Hyper-V
* type: external
* name: Minikube (or anything you like)
* make sure to associate the vSwitch with the correct NIC
* reboot after creating the vSwitch just in case (routing tables, ...)
* go take a look at the network devices on your Windows host to make sure that you have a Virtual Ethernet Adapter configured and actually connected to your network
* Control Panel\Network and Internet\Network Connections. In my case i have: "vEthernet (Minikube)"
Once done make sure to start clean, remove ~/.minikube and remove any VM you tried to create before.
minikube stop
minikube delete
rm -rf ~/.minikube
Once you're ready, make it happen:
minikube start --vm-driver "hyperv" --hyperv-virtual-switch "Minikube" --disk-size 10g --memory 4096 --v 9999 --alsologtostderr
Start a Cluster
C:\windows\system32>minikube start --vm-driver hyperv --hyperv-virtual-switch "minikube-vswitch"
