Can't stop minikube hyper-v VM

[waynesi]

This is a BUG REPORT:

Please provide the following details:

Environment:

Minikube version (use minikube version): v0.28.0

• OS (e.g. from /etc/os-release): Windows 10 Pro 1709
• VM Driver (e.g. cat ~/.minikube/machines/minikube/config.json | grep DriverName): Hyper-V
• ISO version (e.g. cat ~/.minikube/machines/minikube/config.json | grep -i ISO or minikube ssh cat /etc/VERSION): default
• Install tools: Portable binary
• Others:

What happened:

I created the k8s cluster using the command

minikube start --vm-driver="hyperv" --hyperv-virtual-switch="minikube" --kubernetes-version="v1.9.4" --memory=4096

It worked as expected - the VM was created and the cluster was up and running.

Then I tried to shut down the cluster using

minikube stop

The command was hang at 0% for ages and finally end up with the clash report. During the time of waiting, in the Hyper-V manager, I could see the status of the VM was changed to "Shutting down", but the CPU usage was quite low so it didn't look like doing anything. At the end I had to connect to the VM and use shutdown command to turn off the VM.

What you expected to happen:

The cluster should be shutdown as expected.

How to reproduce it (as minimally and precisely as possible):

Simply use the pair of "minikube start ..." and "minikube stop" with parameters as specified above.

Output of minikube logs (if applicable):

Anything else do we need to know:

Rolled back to v0.27.0 and deleted the VM and the %USERDATA%/.kube and .minikube folders to start from scratch. v0.27.0 just worked perfectly as expected.
