Create a docker-machine in AppVeyor build? (Nested Hypervisor needed)

I've tried to run some Docker tests within an AppVeyor CI build, but it currently doesn't work as the AppVeyor build node does not have nested hypervisor enabled to run a 64bit VM within a build.

Is it possible to enable nested virtualization/hypervisor in AppVeyor?

I've also seen that someone tried to run Vagrant in AppVeyor and solved to run 32bit VM's, but docker-machine only has 64bit VM to run docker in it.

    Good question. I have heard that the AppVeyor nodes are running on Azure, right? I don't know exact how to enable in Azure, but it is something that must be enabled in the running VM before running an inner 64bit VM nested into it.

    I only know it from VMware products including vCloud, VMware Workstation and VMware Fusion to enable that feature before starting the outer VM. For VM products it is the switch vhv.enable = "TRUE" in the .vmx file.

    I assume that something similar should be possible in Azure to start the build node VM with 'Virtualize Intel VT-x/EPT...'

    Oh, or is it something that Hyper-V will be able in the next release?

    Exactly, it's going to be available in Windows Server 2016, but Windows Server 2012 Hyper-V (Pro environment) doesn't support that. OSS environment is currently run on Google Compute Engine, not Azure.

    Ah, I see. But is it possible to have a build node on GCE with nested virtualization enabled?
    Or should I try this in a private repo?

    GCE doesn't support that either.

    OK, I see. Seems that Ravello does some other way to get it work.

    Are there any updates regarding running docker containers during build/testing?

    Absolutely! You can now build on Visual Studio 2017 image which is based on Windows Server 2016 and has Docker installed.

    Good to hear! This is not available for VS2015 image? We did not migrate yet.

    Try Visual Studio 2017 image - it has VS 2015 and Docker installed.
