vswitch not found hyperV while running minikube start

10/20/2018

I had created a Virtual switch with the name "Minikube2" . Previously I had created Virtual switch with the name "minikube" ,but deleted it later as there was config issue.

Did all the required configuration -"sharing on ethernet .."

Now when I try to run

minikube start --kubernetes-version="v1.10.3" --vm-driver="hyperv" --hyperv-virtual-switch="minikube2"

it downloads the ISO , but fails to configure the switch -

it says vswitch "minikube2" not found

Short answer is to delete C:\Users\%USERNAME%\.minikube and try again. Below is my investigation:

First I have created Virtual Switch "minikube", started the cluster and it worked as expected. Then I stopped minikube, created new "Minikube2" switch and started minikube

minikube start --kubernetes-version="v1.10.3" --vm-driver="hyperv" --hyperv-virtual-switch="minikube2" --v=9

Appeared issue:

Retrying. E1022 12:50:43.398832 6216 start.go:174] Error starting host: Error starting stopped host: exit status 1 PS C:\Windows\system32>

Then I deleted C:\Users\%USERNAME%\.minikube , minikube vm inside Hyper-V and started again:

C:\Windows\system32> minikube start --kubernetes-version="v1.10.3" --vm-driver="hyperv" --hyperv-virtual-switch="minikube2" --v=9

Result:
