VirtualBox: Effective UID is not root

桌面上运行virtualbox出错:
The virtual machine 'xp' has terminated unexpectedly during startup with exit code 1 (0x1).
Effective UID is not root(euid=1000 egid=482 uid=1000 gid=482)(rc=-10)
Please try reinstalling VirtualBox.

手动敲命令运行/usr/lib/virtual/VirtualBox的出错提示
VirtualBox: Error -10 in SUPR3HardenedMain!
VirtualBox: Effective UID is not root (euid=1000 egid=100 uid=1000 gid=100)
VirtualBox: Tip! It may help to reinstall VirtualBox.

从新安装virtualbox问题依旧, 查看其mode状态
ls -l /usr/lib/virtual/VirtualBox
-rwxr-x--- 1 root vboxusers   35368 4月  15 01:50 VirtualBox

上面这种mode是不对的，须要修改
sudo chmod 4711 /usr/lib/virtualbox/VirtualBox

再次查看
ls -l /usr/lib/virtualbox/VirtualBox
-rws--x--x 1 root vboxusers 35368 4月  15 01:50 /usr/lib/virtualbox/VirtualBox
