So i got vagrant running on a chrome book, kinda.
enable developer mode. enable usb boot and legacy boot. boot into distro of choice go as normal. i used kvm on a linux box to install xubuntu to a thumbdrive and that worked.
mine is an acer c740, and, for some reason, you cant boot from the usb3 port, only usb2. also, the trackpad didnt work with ubuntu 14.04. had to use 15.04. so far, everything else works fine.
