What's the Chinese word for "bare-metal" (computer programming)?
Bare Metal could be tanslated as 裸金属 literally, but it doesn't make sense for Computer Science. I prefer to translate is as 裸机 (Bare machine).

Bare machine


  Bare machine (or bare metal), in computer parlance, means a computer
  without its operating system.


Example from youdao:


  A new remote boot technology based on IP storage area network was
  designed, and the core technology of it is the firmware protocol stack
  running under bare machine platform. 
  
  设计了一种基于IP存储区域网络的远程引导技术，该技术的核心是运行在裸机下的固件协议栈。


From baidu:


  For example, you might choose to allow the results from the virtual
  machines to vary within 10 percent of the results from the bare metal
  control machine.
  
  例如，您可以选择允许来自虚拟机的结果与来自裸机控制机器的结果存在10%的偏差。
