This error means that VirtualBox DHCP server took too long, or failed, to assign an IP address to the device. It is usually caused by the following.

Windows: Hyper-V

On Windows 10/11, this error is usually caused by Hyper-V. Hyper-V does not work well with Genymotion and VirtualBox hypervisor. We recommend turning it off when using Genymotion.

To do so, follow these steps:

1. Disable Hyper-V in Windows features Follow the instructions from this article: How to disable Hyper-V to disable Hyper-V in Windows features.

2. Disable Memory Integrity Windows Memory Integrity security features enforce Hyper-V, even if Hyper-V has been disabled in Windows features. You need to disable this feature to make sure VirtualBox has access to VT-X/SVM hardware virtualization:

3. Verify Hyper-V is properly disabled Open a PowerShell terminal and run the following command: systeminfo | findstr -i "hyper-v requirements" If Hyper-V is properly disabled, it should return: Hyper-V Requirements: VM Monitor Mode Extensions: Yes Otherwise, Hyper-V is still enabled. Make sure that you have disabled Memory Integrity in Windows Security as well as Hyper-V in Windows features. Note: If disabling Hyper-V in Windows features and Memory Integrity in Windows Security does not disable Hyper-V, you can try following this guide to completely remove Hyper-V.

Power management

This error can also be caused because VirtualBox took too long to allocate an IP to the device. On Laptops and Notebooks, this may happen if you are in "Save Battery" power mode. To avoid this, make sure to set your power mode to "Performance" and plug the AC power in. Please note that virtualization is CPU-intensive and may drain your battery.

Laptops with discrete GPU

Some laptops have a discrete NIVIDIA or AMD GPU alongside an Intel iGPU. This type of hardware is known to cause issues on Windows systems (errors, slowness, crashes). You need to force Windows to use the discrete, high-profile GPU globally to fix this issue. To do so, follow the instructions from this article: How to fix issues on Windows with laptops using hybrid graphics (dual GPU)?

Windows Updates

This error may occur after a Windows update. To fix it, remove and re-install VirtualBox:

If an error occurs, reboot your PC and try launching Genymotion Desktop again. Note: Sometimes, Windows updates re-enable Hyper-V and/or Memory Integrity. If re-installing VirtualBox does not help, verify that Hyper-V and Memory Integrity are properly disabled. If not, repeat the steps from the article: How to disable Hyper-V

Other

macOS and Linux It is possible to use QEMU instead of VirtualBox. While not recommended on Windows systems, QEMU has better compatibility and performances on Linux and macOS.

You are trying to run 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, 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?

VPN and Firewalls

VPN and Firewalls may interfere with VirtualBox. See: Genymotion Desktop and VPN Genymotion Desktop and firewalls

Hardware requirements

This error may occur on hardware which does not meet Genymotion Desktop requirements.

The virtual device is using too many CPUs

You cannot use all your CPU cores when running a virtual device: you need to preserve 1 or 2 cores for your operating system. For example, if your CPU has only 8 cores, you should to reduce the number of Processors of the virtual device to 6 or less. You should not need more than 4 CPUs for a virtual device to run Android 10 or above comfortably.
