在VirtualBox的Ubuntu虛拟機裡試圖本地安裝Kyma（一個基于Kubernetes的開源架構）時，遇到下面的錯誤資訊：

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

我使用的虛拟機軟體是VirtualBox, 裡面已經設定了啟用虛拟化技術 VT-x/AMD-V:
根據這個錯誤資訊在Stack Overflow上查詢，發現一條線索：
https://superuser.com/questions/1138980/this-computer-doesnt-have-vt-x-amd-v-enabled-enabling-it-in-the-bios-is-mandat 簡單得說，VirtualBox不支援在虛拟機裡開啟另一個嵌套的虛拟機。如果确實需要運作這種嵌套的虛拟化場景，需要嘗試VMWare Workstation 11.
