I have a Dell Optiplex 9010, amd64, currently running xenial 16.04
I was following this thread: VirtualBox - RTR3InitEx failed with rc=-1912 (rc=-1912)
I'll try other distros. Virtualization is enabled in BIOS from what I can tell.
I'm just not sure if the host OS freezing means anything right off the bat.
I am using a 64bit guest os (Ubuntu also). I'll try Debian next (though isn't Ubuntu based on Debian/vice versa) maybe I should try 32bit
Desktop has quad core, set 1 core for VM with 1GB RAM (has 16GB)
I'll also try disabling Vt-x I saw that in the VBox setup
edit: Debian froze too
edit: will post on the Vbox forums, probably where I should have been from the start. Forgot I used to post there.
