Normally when launching the "linux terminal" on ChromeOS aka crostini - a kvm is created with lxc, the default penguin container and any additional containers run as lxc containers inside inside this vm.

baguette appears to allow launching linux directly as virtual machines, skipping the lxc portion. Based on the flags this seems to potentially provide things like pci passthrough which would make chromeos even more versatile.

Currently it's possible to launch kvms from crostini but it happens from inside the lxc container using nested virtualization.
