When booting under KVM the following error messages are issued:
hypfs.7f5705: The hardware system does not support hypfs
hypfs.7a79f0: Initialization of hypfs failed with rc=-61
While being documented, they can easily be avoided by bailing out of
hypfs_init() early in case of running as a KVM guest.
