I am trying to run Virtual Box VM inside VMWare VM (Windows Server 2008 64 bit)
I am getting below error on booting virtual box vm.
Stderr: VBoxManage.exe: error: VT-x is not available (VERR_VMX_NO_VMX) VBoxManage.exe: error: Details: code E_FAIL (0x80004005), component ConsoleWrap, interface IConsole
I have enabled VT-X virtualization setting on the VMWare VM.
and Hyper-V is not installed on VMWare VM (Windows Server 2008).
Also on the Virtual Box – i could see options for installing only 32 bit guests (Even though Windows Server 2008 is 64 bit)
I am not sure what else i could be missing?

At 2018, VirtualBox does not support nested virtualization. There is a feature request for a while, but it is not implemented nowadays.
According to different reports, nested virtualization are supported to run in other systems. For instance:
William Lam has a blog page with several articles on nested virtualization.
