Why my genymotion block in the start the virtual device?

There are a few common reasons Genymotion Desktop can get stuck starting a virtual device, especially on Windows. Try these steps in order:

• Check system and version compatibility
• Genymotion Desktop requires a supported OS and the latest release. Windows 7 is not supported. If you’re on an older Windows edition, upgrade to a supported OS (Windows 10/11) or use a supported macOS/Linux environment. See Windows troubleshooting and “Unable to start the Virtual Device” guidance for specifics. https://genymotion.com/blog/windows-troubleshooting/ (Windows troubleshooting hub) and https://genymotion.com/blog/on-demand-4-1 (Unable to start the Virtual Device article)

• Verify virtualization and BIOS/firmware settings
• Ensure VT-x/SVM virtualization is enabled in your BIOS/firmware and that your CPU supports virtualization. Then retry starting the device.
• If you recently updated Windows, try rebooting after making sure virtualization is still enabled.

• Check Hyper-V and VirtualBox conflicts
• Genymotion Desktop runs with VirtualBox. If Hyper-V is enabled, it can block VirtualBox from starting VMs. Disable Hyper-V and related features, then restart Genymotion and try again. See the Windows troubleshooting guidance for related conflicts. https://genymotion.com/blog/windows-troubleshooting/

• Ensure Genymotion Desktop is the latest release
• We only support Genymotion’s latest release. If you’re on an older build, update to the latest desktop version and retry.

• Avoid running Genymotion inside a VM or cloud environment
• Genymotion Desktop is designed for non-virtual environments and may fail if you’re running it inside another VM or unsupported hosts. See the “Unable to start the Virtual Device” guidance for environment notes. https://genymotion.com/blog/on-demand-4-1

• Check for specific error messages
• If you see messages like “VBoxHeadless.exe - Application Error” or “memory could not be read,” follow the Windows-specific troubleshooting steps in the Windows article linked above.
