Error VT-x not available for Vagrant machine inside Virtualbox

I have an Ubuntu Virtual machine that is configured to have VT-x enabled, 6 Processors, and 25 GB RAM.

Inside that virtual machine I am trying to start a vagrant machine with the following configuration:

master.vm.box = "precise32"
master.vm.provider "virtualbox" do |vb|
    vb.customize ["modifyvm", :id, "--cpuexecutioncap", "80"]
    vb.memory = 10000
    vb.customize ["modifyvm", :id, "--cpus", "2"]   
    vb.customize ["modifyvm", :id, "--ioapic", "on"]
end

When I start the Vagrant I get the error VT-x not enabled.

I tried both 32 bit and 64 bit versions of Vagrant but still no luck.

Any idea how can I run Vagrant machine inside the Virtualbox?

Solution

  • UPDATED: As pointed out below, you can use nested VirtualBox + vagrant provided that only 1 virtual CPU is assigned to the nested VM, plus nested VM guest is 32-bit OS.
