# will flood /var/log/messages with messages like:
# "hv_utils: KVP: user-mode registering done."
# This is also caused by old hyper-v.rpms which have a restart command
# in their post install script. Catch those old kernels and avoid the
# flood, which will easily fill the root partition during an upgrade.
