Failed to open a session NS_ERROR_FAILURE (0x80004005)

Virtual machine sessions terminate unexpectedly. VM does not show any logs. So here is some of the returns from the program. The attached file contains all the info I have gathered along with the contents of the file dmesg.

Oracle Virtual Box

Problem solved. UEFI boot is the cause of my problem. See this webpage for more details and a resolution: http://askubuntu.com/questions/760671/c ... keep-secur.
