The article explains the situations in which the error occurs.
1. Genymotion Desktop in a virtual machine
- Genymotion Desktop has been designed to run in a physical environment, not in a virtual machine.
- Nested virtualization is not supported.
- Genymotion Desktop will not work if run in a Windows, Linux or macOS VM.
- For more details, refer to Can Genymotion Desktop run in a virtual machine?
2. Your CPU does not meet Genymotion hardware requirements
- Genymotion needs hardware virtualization to run.
- While almost any recent CPU supports this feature, some low-end CPUs don't.
- Make sure that your CPU meets Genymotion Desktop requirements.
3. Hardware Virtualization (VT) is disabled
- Hardware virtualization is the capability that allows a computer to run virtual machines.
- For Intel CPUs, this feature is called VT-x.
- For AMD CPUs, this feature is called SVM.
- All modern CPUs support hardware virtualization, but this feature may be disabled by default.
- Check that Intel VT-x, AMD-V and/or SVM is enabled in your computer BIOS/UEFI.
- Please refer to your computer manufacturer user guide to find how to access the BIOS/UEFI.
- If you are using a computer with Windows pre-installed, you may not be able to access it at start-up.
- In this case, follow the instructions from these articles: How to enable Virtualization (VT-x/SVM) on Windows 10? How to enable Virtualization (VT-x/SVM) on Windows 11?
4. Windows + Hyper-V
- VirtualBox falls back to software virtualization when Hyper-V is active.
- This causes multiple issues and compatibility problems with Genymotion Desktop, including this error.
- At this time, we strongly recommend disabling Hyper-V when using Genymotion Desktop on Windows.
- For detailed instructions, please refer to How to disable Hyper-V in Windows?
