  "account": "A customer requested Docker on a Windows Server VM hosted on a KVM-based hyperconverged platform, without nested virtualization enabled. The two main traps that prevented Docker from working were Docker Desktop and Windows containers in Hyper-V isolation. Docker Engine and Windows containers in process isolation were the two viable options that worked without nested virtualization. This issue is common in Windows VMs on KVM-based platforms and private clouds where nested virtualization is off by default. The main reason it often goes unnoticed during testing is because Docker Desktop hides all the necessary details. The solution involves installing Docker Engine, ensuring the host build matches the image build, and disabling Microsoft Defender Controlled Folder Access.",
  "summary": "A presales field note about a customer who wanted Docker on a Windows Server VM — on a platform with no nested virtualization — the two traps I hit proving it works, and the one check that made the whole question disappear. The request came in short and sure of itself. \"We need Docker on our Windows server. Our developers ship containers.\" The server was a Windows Server VM on a KVM-based…",
