Unable to start Docker Container in Windows 10

Question

I am using Windows 10 pro and successfully installed Docker Client 18.09.0 and fetched hello-world docker image.

But when I try to run the image in container using docker run, it is giving the below error

C:\Program Files\Docker\Docker\Resources\bin\docker.exe: Error response from daemon: CreateComputeSystem 7b206637bedeb11c5f4bb8a5c12f941da3980a5c0e6e18d823f3323b6640a9de: The virtual machine could not be started because a required feature is not installed.

I am not sure what sure about the issue or what feature is not installed. When I searched the internet all the errors are about hyperv which is there in my environment. My docker info gives the below details by the way:

Just in case someone is using a Windows 10 Virtual Machine like me you can use the following command in power shell.

Set-VMProcessor -VMName my_virtual_machine -ExposeVirtualizationExtensions $true

Remember to run as Administrator before executing the command else it will give you an error saying you don't have permissions.
