Upgrading to Win 11: Turtle Icon Always Appears in VirtualBox Guest VM
While upgrading from Windows 10 to Windows 11, some users have noticed a peculiar issue where a turtle icon always appears in their VirtualBox Guest VM. This article aims to provide a detailed explanation of the potential causes and solutions for this problem.
Understanding Virtualization Features
Virtualization is a technology that allows multiple operating systems to run on a single physical machine as virtual machines (VMs). There are several virtualization software available, including VirtualBox, VMWare, and Hyper-V.
Hyper-V is a native virtualization solution in Windows, while VirtualBox is a popular third-party virtualization software. Sometimes, enabling Hyper-V can interfere with VirtualBox's operation, leading to the infamous turtle icon.
The Turtle Icon in VirtualBox
In VirtualBox, a turtle icon appears when the VM is experiencing a significant performance degradation. This icon indicates that the VM is running in "background mode," where it gets lower CPU priority compared to other applications running on the host machine.
If the turtle icon appears even when the host machine has sufficient resources, it could be due to a conflict between Hyper-V and VirtualBox.
Resolving the Turtle Icon Issue
A possible solution is to disable Hyper-V before launching VirtualBox. To do this, follow these steps:
- Press Windows key + X and choose "Windows PowerShell (Admin)" or "Command Prompt (Admin)"
- Type
"bcdedit /set hypervisorlaunchtype off"and press Enter - Restart your computer
After disabling Hyper-V, try launching your VirtualBox VM again. If the issue persists, there might be a conflict with VirtualBox Extensions. You can try reinstalling VirtualBox and its extensions to resolve the conflict.
Alternative Solutions
If the above solution does not work, you can consider the following alternatives:
- Dual Boot: Instead of using virtualization software, you can dual boot your machine with Windows 11 and your previous operating system.
- Use a Different Virtualization Software: If VirtualBox does not work as expected, you can try using other virtualization software like VMware or QEMU.
When upgrading from Windows 10 to Windows 11 and encountering the turtle icon issue in VirtualBox Guest VM, check for conflicts between Hyper-V and VirtualBox. Disable Hyper-V or try alternative solutions if necessary.
