I have attempted to run Genymotion Android emulator by following the User Guide, but am getting the following error:

Unable to start the virtual device.

VirtualBox cannot start the virtual device.

To find out the cause of the problem, start the virtual device from VirtualBox.

For more information, check the log files. Please refer to: https://www.genymotion.com/#!/support?chapter=collapse-logs#faq

Can anyone suggest how I can resolve this?

Enter to BIOS and look for an option named "Intel Virtualization Technology", "Intel VT-x", "Virtualization Extensions", "Vanderpool" or something similar. Enable the option and select “Save and Exit” or the equivalent feature to save your settings changes and reboot your computer.

My suggestion is to forget Genymotion and VirtualBoxas they are very bad. Download Droid4x it is very easy to test apps with.

One thing to do when you download and install it, is to go to Settings -> Developer Tool Debuging and turn it on.

Good luck.

Change the virtualBox to 4.3.12

Delete the virtualBox and download from https://www.virtualbox.org/wiki/Download_Old_Builds_4_3_pre24 choose 4.3.12

my computer is windows7 and it works.

Really old question but to solve it you can try to download VirtualBox latest version

It solved the problem for me already twice. First time when I first downloaded GenyMotion that came with an old incompatible version of VirtualBox. After a couple of months the problem appeared in GenyMotion again and a VirtualBox upgrade solved it again.

This is because either you have changed the Virtualbox host-only settings or have completely deleted the Virtualbox host-only in the network connection window. To fix this, just uninstall the virtualbox and genymotion once and install Virtualbox and Virtualbox sdk first, and then install genymotion.
