Windows - Unable to start the Virtual Device
Every time Genymotion Desktop is launched, it calls VirtualBox to verify the availability of at least one VirtualBox Host-Only Ethernet Adapter. If none is available or compatible, it tries to create a new one and repeats the verification process. A VirtualBox Host-Only Ethernet Adapter is a network adapter used by VirtualBox to provide host-only networking. This operation sometimes fails on Windows. To solve this, try the workarounds below.
1. Reboot your PC
Rebooting your PC after having launched Genymotion Desktop for the first time often fixes this error.
2. Reinstall VirtualBox
If rebooting your PC does not help, you can first try to re-install VirtualBox:
- Remove VirtualBox from Windows.
- Reboot your PC.
- Download VirtualBox recommended version installer – see VirtualBox recommended versions.
- Re-install VirtualBox.
- Launch Genymotion Desktop.
- Do not launch a device yet or you will get an error!
- Reboot your PC.
- Launch Genymotion and start a device.
3. Fix the VirtualBox host-only network interface
If none of the above work, try the following:
- Open Windows Device Manager and go to Network adapters.
- You may see 3 VirtualBox Host-only Ethernet Adapters and one is disabled.
- Left-click on the disabled host-only interface and select Uninstall device.
- You should now have only 2 VirtualBox Host-only adapters.
- Left-click on the second VirtualBox host-only adapter (usually called VirtualBox Host-Only Ethernet Adapter #2) and select Update driver:
- Select Browse my computer for drivers
- Select Let me pick from a list of available drivers on my computer
- Select the driver called VirtualBox Host-Only Ethernet Adapter and click Next
- Close the Device Manager and start Genymotion Desktop.
- If this still does not help, please refer to Windows/VirtualBox - An error has occurred while trying to create a virtualbox host-only network interface for other possible solutions.
