问题
安装Parallel Tools 在kali或者其他linux系统中，可能会出现以下报错：
An error occurred when installing Parallels Tools. Please go to /var/log/parallels-tools-install.log for more information.
打开后发现是类似这样的报错

阅读后明显发现，是could not build kernel modules 与failed to install kernel modules出现问题
网上没有很完整的解决办法，这里写一篇帖子详细描述下
查阅资料发现，是linux升级内核版本后修改了一个参数的名字，详情见内核修改清单，导致编译时无法调用参数里的结构体。
我们将cd中的内容全部复制出来。
步骤一
解压kmods目录的prl_mod.tar.gz
cd kmods tar -xzf prl_mod.tar.gz
将以下文件中的“file_operations”修改为“proc_ops”
prl_fs/SharedFolders/Guest/Linux/prl_fs/
–prlfs_compat.h
修改后：
–super.c
修改前：
修改后：
prl_fs_freeze/Snapshot/Guest/Linux/prl_freeze
–prl_fs_freeze.c
修改后：
–prlfs_freeze_compat.h
修改后：
prl_tg/Toolgate/Guest/Linux/prl_tg
–prltg_common.h
修改后：
–prltg.c
修改后：
prl_vid/Video/Guest/Linux/kmod
–prlvtg.c
修改后：
步骤二
修改完成后使用make命令查看是否报错
无报错使用make clean清除后重新打包
rm prl_mod.tar.gz tar -zcvf prl_mod.tar.gz .
若报错：'ERROR: "call_tg_sync" [/usr/lib/parallels-tools/kmods/prl_fs/SharedFolders/Guest/Linux/prl_fs/prl_fs.ko] undefined!
请在prl_fs/SharedFolders/Guest/Linux/prl_fs/Makefile添加
KBUILD_EXTRA_SYMBOLS := /usr/lib/parallels-tools/kmods/prl_tg/Toolgate/Guest/Linux/prl_tg/Module.symvers
在prl_vid/Video/Guest/Linux/kmod/Makefile添加相同语句
重新打包
rm prl_mod.tar.gz tar -zcvf prl_mod.tar.gz .
运行./install，即可正常安装parallel tools
