For three days I've got problems with the VirtualBox and I can not find a solution.
For more than a year I have been working on a VirtualBox on Ubuntu host and a guest of windows7 It worked great, but of a few days ago can not run windows I get this message Failed to open a session for the virtual machine![]()
