Ubuntu – How to Fix VT-x Error When Setting Up VirtualBox

Ubuntuvirtualboxvt-x

I have tried to setup VirtualBox on Ubuntu, but I get this error even though Intel virtualization technology (VT-x) is set to Yes in the BIOS:

Failed to open a session for the virtual machine Ubuntu.

VT-x is disabled in the BIOS for both all CPU modes > (VERR_VMX_MSR_ALL_VMX_DISABLED).

Result Code: E_FAIL (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

EDIT: according to SecurAble my system is able to handle virtualization:

What solved my issue was using less than 3 GB of ram in the virtual box session. I was originally attempting to utilize roughly 6 GB.

You are trying to allocate >3GB of RAM to the VM. This requires: (a) a 64 bit host system; and (b) true hardware pass-through ie VT-x.
