錯誤訊息 This computer doesn't have VT-X/AMD-v enabled

在VirtualBox的Ubuntu虛擬機器裡試圖本地安裝Kyma（一個基於Kubernetes的開源框架）時，遇到下面的錯誤資訊：

E0827 11:19:38.972489 3093 start.go:174] Error starting host: Error creating host: Error executing step: Running precreate checks.

: This computer doesn't have VT-X/AMD-v enabled. Enabling it in the BIOS is mandatory.

Retrying.

我使用的虛擬機器軟體是VirtualBox, 裡面已經設定了啟用虛擬化技術 VT-x/AMD-V:

根據這個錯誤資訊在Stack Overflow上查詢，發現一條線索：

簡單得說，VirtualBox不支援在虛擬機器裡開啟另一個巢狀的虛擬機器。如果確實需要執行這種巢狀的虛擬化場景，需要嘗試VMWare Workstation 11.
