ubuntu virtualbox安装后打开出错
1. 打开virtualbox后，双击系统名出错:
中间显示蓝色字体错误： '/etc/init.d/vboxdrv setup'
解决方法：
在命令行中执行 sudo /etc/init.d/vboxdrv setup
还是出错， 安装网上的方法重装dkms:
sudo apt-get autoremove dkms
sudo apt-get install dkms
完后再执行sudo /etc/init.d/vboxdrv setup
root@li-desktop:~/Downloads# sudo /etc/init.d/vboxdrv setup
* Stopping VirtualBox kernel modules [ OK ]
* Uninstalling old VirtualBox DKMS kernel modules [ OK ]
* Trying to register the VirtualBox kernel modules using DKMS
Error! Your kernel headers for kernel 2.6.35-31-generic cannot be found at
/lib/modules/2.6.35-31-generic/build or /lib/modules/2.6.35-31-generic/source.
* Failed, trying without DKMS
* Recompiling VirtualBox kernel modules
* Look at /var/log/vbox-install.log to find out what went wrong
还是出错，继续如下安装linux-headers-2.6.35-31-generic后重试
sudo apt-get install linux-headers-2.6.35-31-generic
sudo /etc/init.d/vboxdrv setup
2. 打开virtualbox后， 导入系统安装文件winxp.iso时出问题了：
Failed to open a session for the virtual machine xp.
Failed to load VMMR0.r0 (VERR_SUPLIB_WORLD_WRITABLE).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}
解决方法： sudo chmod -R o-w /usr
