This error usually happens in the following situations:
1. You are running Genymotion Desktop in a virtual machine
Genymotion Desktop has been designed to run in a physical environment, not in a virtual machine. For this reason, nested virtualization is not supported and Genymotion Desktop will not work if run in a Windows, Linux or macOS VM.
For more details, please 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 support this feature, some low-end CPUs don't. Make sure that your CPU meets Genymotion Desktop requirements.
3. Hardware Virtualization (VT) is disabled
All modern CPUs support hardware virtualization (VT-x/SVM), 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, just follow the instructions from this article: 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?.
