The VirtualBox DHCP server has not assigned an IP address to the virtual device

The VirtualBox DHCP server has not assigned an IP address to the virtual device. The VirtualBox DHCP server took too long to assign an IP address to the device, or failed to assign an IP address. On Windows, Hyper-V is a common cause. Hyper-V does not work well with Genymotion and the VirtualBox hypervisor. We recommend turning Hyper-V off when using Genymotion. To do so, follow these steps.

Windows

Hyper-V

• Disable Hyper-V in Windows features.
• Follow the instructions from this article: How to disable Hyper-V to disable Hyper-V in Windows features.
• Disable Memory Integrity.
• Windows Memory Integrity security features enforce Hyper-V, even if Hyper-V is disabled in Windows features. You need to disable Memory Integrity to make sure VirtualBox has access to VT-X/SVM hardware virtualization.
• Open Windows Security.
• Go to Device Security > Core isolation details.
• Turn Memory Integrity off.
• Verify Hyper-V is properly disabled.
• Open a PowerShell terminal.
• Run the command: systeminfo | findstr -i "hyper-v requirements".
• If Hyper-V is properly disabled, the command should return: Hyper-V Requirements: VM Monitor Mode Extensions: Yes.
• If Hyper-V is not disabled, Hyper-V remains enabled. Ensure Memory Integrity in Windows Security is disabled as well as Hyper-V in Windows features.
• If this does not work, refer to How to disable Hyper-V in Windows? for other methods.

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, set your power mode to "Performance" and plug the AC power in.
• Virtualisation is CPU-intensive and may drain your battery.

Laptops with discrete GPU

• Some laptops have a discrete NVIDIA 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:
• Uninstall VirtualBox
• Reboot your PC
• Download VirtualBox recommended version installer for Windows. See VirtualBox recommended versions
• Re-install VirtualBox
• Reboot your PC
• Launch Genymotion and start a device.
• 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 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.
