問題：
win7 操作系統 ，vmware12 重新安裝，centos7 從其他電腦拷貝過來；
1. vmtool 安裝失敗：
/tmp/modconfig-oAfYr7/vmhgfs-only/page.c:1649:23: warning: passing argument 3 of ‘wait_on_bit’ makes integer from pointer without a cast [enabled by default]
TASK_UNINTERRUPTIBLE);

解決：
把vmtool 壓縮包裏面的 lib/modules/source/vmhgfs.tar 拷貝到臨時目錄，解壓，然後修改裏面的 page.c 文件如下：
//#if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 19, 0)
#if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 10, 0)
把修改後的文件打包成 vmhgfs.tar ，然後覆蓋lib/modules/source/vmhgfs.tar
重新執行vmtool 腳本；
2. 成功安裝了vmtool 後，/mnt/hgfs 下仍然空空如是，試了網上一些方法，ls /mnt/hgfs, 更加糟糕，顯示如下：
cannot access ‘hgfs’: Protocol error
解決辦法：
1) VMWARE 中把centos7 關閉；
2) 重新設置需要的共享文件夾；
3) VMWARE 中啓動centos7;
如果還不行，那得重新嘗試百度的各種方法了；
