Docker – Install Docker on Windows Server 2016 virtual machine

This is a common issue in the worl of PtoV, VtoP etc, but I always forget the resolutions that have worked for me.

One that springs to mind is deleting the ACPI device from Device Manager

But here is something thats looks similar to your issue, given that your event log shows all cpus.

Browse to c:\windows\system32
Right click on HAL.DLL
Click the version tab
Click Internal Name.  Here it will tell you definitly which HAL you are running.

You want halmacpi, not halaacpi

I've created a clustered Hyper-V setup within VMWware Workstation on my windows 7 laptop from scratch. I would assume you could run the demo environment as well.

I will say, performance is generally pretty terrible when running nested virtualization solutions but it does work. Load up on RAM before even thinking about trying to run something like this.
