VERR_VMX_NO_VMX, rc=E_FAIL (0X80004005) - VirtualVM is not running in Windows10


Problem:
1.    I am using Oracle VirtualVM and installed Ubuntu .
2.    I have installed Docker recently.
Now, When I tried to access the Ubuntu from VirualVM.
I am getting the following error message.


Solution: 
In Windows 10.
Type Run  > CMD > bcdedit /set hypervisorlaunchtype off

Information of each part:
BCDEdit 
BCDEdit is a command-line tool for managing Boot Configuration Data (BCD). BCD files provide a store that is used to describe boot applications and boot application settings.
Hypervisor
A hypervisor is a computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine

When you don't have virtualization enabled, your system acts like this:
[ Hardware ] -> [ Operating System ] -> [ Applications ] -> [ You ]

When you do with Hyper-V, there's an extra layer in there:
[ Hardware ] -> [ Virtualization Hypervisor ] -> [ One of possibly several OSes ] -> [ Applications under that OS ] -> [ You ]
