This feature profile enables the hypervisor_guest USE flags for every chromeos-kernel package. It speeds up CrOS running as a guest on hypervisor.

To add this profile to an existing overlay, take the following steps:

1. Create a new subdirectory within the given overlay's “profiles” directory.
2. Add a “parent” file to the new subdirectory with the below two lines:

../base
chromiumos:features/kernel/hypervisor-guest

The first line specifies that the new profile will inherit from the overlay's base profile. The second line will mix in this profile which enables the hypervisor_guest USE flags for the chromeos-kernel package, independent of which kernel version the overlay uses.
