自从升级到Ubuntu 14.04以来,启动VirtualBox虚拟机时,我得到:
Failed to open a session for the virtual machine win7pro32bit.
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).
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: Console
Interface: IConsole {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}
sudo apt-get purge virtualbox
sudo apt-get autoremove
sudo apt-get update
sudo apt-get install virtualbox
更新:在现有Ubuntu 14.04中将VirtualBox本身升级到5.0时也会发生。
