I just got a new work laptop but I am having a lot of difficulty getting VirtualBox to run on it. It basically fails to start the virtual machine when I try boot it and remains stuck on "Starting Virtual Machine"
Looking at dmesg is proving very cryptic for me:
$ dmesg | grep vbox

I have installed virtualbox on many different work laptops (including the same model laptop from a previous generation) and never had any issues.
I have enabled virtualization from setup so that is not the issue. I have also rebuilt virtualbox several times in case it failed to compile against the current kernel correctly.
Is there something from dmesg that points to a fundamental flaw or something that I am completely overlooking?
Any help would be appreciated as it's prevented me from getting any work done which is extremely frustrating.
