ls -l /
drwxr-xr-x  13 abc  test   4096 6月   7 2012 usr
发现/usr不属于root用户
解决方法：
sudo chown root:root /usr/
如果还是不行，再检查下/usr/lib是否属于root,用上面方法解决。

问题
不能为虚拟电脑 xp 打开一个新任务.
Implementation of the USB 2.0 controller not found!
Because the USB 2.0 controller state is part of the saved VM state, the VM cannot be started. To fix this problem, either install the 'Oracle VM VirtualBox Extension Pack' or disable USB 2.0 support in the VM settings (VERR_NOT_FOUND).

解决方法安装virtualbox extension pack
/> 下载
Oracle VM VirtualBox Extension Pack
VBoxGuestAdditions
这两个包
我安装的是virtualbox 4.3.20,选择下载4.3.20的的

安装:
VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.3.20.vbox-extpack
虚拟机上--设备--分配光驱--选择一个光驱   选择下载的VBoxGuestAdditions_4.3.20.iso ,就会自动开始安装,根据提示操作就可

问题:Kernel driver not installed (rc=-1908)
解决:
sudo modprobe vboxdrv
如果还是不行,查看下这有没安装有 kernel-devel如果没有,安装它

zengming@linux-eshv:~> sudo /etc/init.d/vboxdrv setup                                                                                                                    
Recompiling VirtualBox kernel module, NOT. It has been packaged.                                                                                             done        
zengming@linux-eshv:~> sudo /etc/init.d/vboxdrv restart
redirecting to systemctl restart vboxdrv.service                                                                                                                         
Failed to restart vboxdrv.service: Unit vboxdrv.service failed to load: No such file or directory. // 出现这种错误有可能是dkms没有安装,安装完dkms
