Help with "critical error" - trying to create Virtual Machine with virtualbox

User_JQC1X

I am attempting to create a virtual machine on a MacBook Pro using Virtual Box. My goal is to install MacOS Yosemite on the virtual machine. When I start up the virtual Machine I get the following error: " A critical error has occurred while running the virtual machine and the machine execution has been stopped". I have attached the log and png files to my post. If anyone can give some guidance on how to solve this error it would be greatly appreciated.
