我发现有人在PintOS之前问了一个相关的问题，内核对ubuntu 上的-v选项bochs感到恐慌
然而，我试过了，但没有成功。"pintos——多次运行警报"似乎很好，但当我进行"检查"时
......

我今天遇到了同样的问题，因为我试图将qemu设置为默认模拟器，所以我将utils/pintos中的第103行更改为
$sim = "qemu" if !defined $sim;
但我忘记将threads/Make.vars中的SIMULATOR值更改为
SIMULATOR = --qemu
由于我没有在我的机器上设置bochs，make check试图在它上运行测试，但如果无法启动。
注意这是测试无法运行的一种情况，这可能是另一个原因，但由于
pintos -- run alarm-multiple
工作正常，我想这可能和你的问题一样。
