Here is a solution if you are getting this error on an Azure Windows 10 VM where you have installed Docker and this is already Nested Virtualization capable VM in other words your Azure VM must be V3 sized as minimum (DV3 or EV3):
- Ensure Windows Hyper-V featutes are enabled by running PowerShell cmdlet:
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All -Verbose
- Ensure Windows Containers feature is enabled by running PowerShell cmdlet:
Enable-WindowsOptionalFeature -Online -FeatureName Containers -All -Verbose
- Ensure Hypervisor is set to auto start in the Boot Configuration Database (BCD) by running in elevated command prompt the command:
bcdedit /set hypervisorlaunchtype Auto
After running all of the above and you restart the Azure VM, Docker should be starting normally.
In addition to the Answer above the PowerShell cmdlet to set the Virtual Machine Setting is:
Set-VMProcessor -VMName <Enter-VM-Name> -ExposeVirtualizationExtensions $true -Verbose
Still have an issue and haven’t rebooted yet?! – just restart the windows services by running the following:
net stop vmms
net start vmms
