Over the last year I’ve been utilising Docker more and more. Today I needed to fire up an old virtual machine that I use a couple of times a year. The VM is in VirtualBox. It wouldn’t start. The error was;
Raw-mode is unavailable courtesy of Hyper-V. (VERR_SUPDRV_NO_RAW_MODE_HYPER_V_ROOT)
Docker Desktop for Windows uses Microsoft Hyper-V for virtualization, and Hyper-V is not compatible with Oracle VirtualBox. Therefore, you cannot run the two solutions simultaneously.
Now I wasn’t going to go to the trouble of migrating my VM from Virtual Box to Hyper-V for the 1 to 2 times a year I need to use it. And I wasn’t going to migrate it to Azure for the little use it gets either.
After some Googling I found the answer. Temporarily disable Hyper-V. In an elevated PowerShell session run;
Disable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor
After a restart Virtual Box will start the VM. When finished with VirtualBox run;
Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor
After a restart Docker and Hyper-V are back in action.
Posting this will let me find it quickly next time. Maybe it’ll help someone else too.
