Genymotion: “The specified virtual device was not found in VirtualBox list”

Question

One day I tried to launch a Genymotion virtual device and got:

Everything used to work fine. I haven't done any update. I use Genymotion 2.3.1 and Oracle VirtualBox 4.3.12 on Windows 7 SP1 x64 Ultimate. What could have caused the issue to arise, and how to fix it?

My configuration:

When I tried to launch the VM from VirtualBox, I get:

Failed to open a session for the virtual machine Samsung Galaxy S5 - 4.4.4 - API 19 - 1080x1920.

The VM session was closed before any attempt to power it on.

Result Code: E_FAIL (0x80004005)
Component: SessionMachine
Interface: ISession {12f4dcdb-12b2-4ec1-b7cd-ddd9f6c5bf4d}

Answer 1

@Frank,

Your VM is in a saved stated. You will need to turn it to a powered off state or discard the saved state via the Virtual Box App.
