minikube: Localkube crashed on Hyper-V

Minikube version (use minikube version): v0.21.0

Environment:

• OS (e.g. from /etc/os-release): Windows 10 Enterprise 10.0.15063 build 15063
• VM Driver (e.g. cat ~/.minikube/machines/minikube/config.json | grep DriverName): hyperv
• ISO version (e.g. cat ~/.minikube/machines/minikube/config.json | grep -i ISO or minikube ssh cat /etc/VERSION): minikube-v0.23.0.iso
• Install tools: Chocolatey
• Others:

What happened: Either after restarting my laptop, or after being idle for a while, minikube appears to cease responding and is unable to restart.

Attempt to access the dashboard ends with:

minikube dashboard
Could not find finalized endpoint being pointed to by kubernetes-dashboard: Error validating service: Error getting service kubernetes-dashboard: Get https://192.168.0.185:8443/api/v1/namespaces/kube-system/services/kubernetes-dashboard: dial tcp 192.168.0.185:8443: connectex: No connection could be made because the target machine actively refused it.

Minikube sometimes is successfuly starting after doing:

• minikube stop
• minikube delete
• rd /s ~/.minikube
• minikube start --vm-driver hyperv --hyperv-virtual-switch External --alsologtostderr

The above is not always successful and I’m unable to determine why. Typically the process freezes after downloading the ISO.

What you expected to happen: I expect minikube to start succesfully.

How to reproduce it (as minimally and precisely as possible): Restart the machine or stop using the dashboard/kubectl for a while.
