Public bug reported:
The /usr/sbin/hv_kvp_daemon script installed by the hv-kvp-daemon-init
package currently fails to find the hv_kvp_daemon binary for the running
kernel when running under a 3.11 release (as per a reasonably up-to-date
Ubuntu 12.04 installation). Ironically, the hv_kvp_daemon script
installed by linux-tools-common package works fine, however, it is
diverted by the package ending up at /usr/sbin/hv_kvp_daemon.hv-kvp-
daemon-init. It is thus never actually called by the hv-kvp-daemon init
script.
The hv-kvp-daemon-init package is still required as it installs various
other support utilities as well as the init script itself used to start
the KVP (Key-Value Pair) daemon. I believe this issue has arisen as the
/usr/sbin/hv_kvp_daemon script was presumably not included until the
linux-tools-common releases associated with the 3.11 series of kernels
and has not been updated to reflect this.
A simple workaround for now is to remove the divert and restore the script
installed by linux-tools-common:
sudo dpkg-divert --remove /usr/sbin/hv_kvp_daemon
sudo mv /usr/sbin/hv_kvp_daemon /usr/sbin/hv_kvp_daemon.bak
sudo mv /usr/sbin/hv_kvp_daemon.hv-kvp-daemon-init /usr/sbin/hv_kvp_daemon
sudo service hv-kvp-daemon-init start
ps -ef | grep kvp # Verify the daemon is actually running
For the unaware, the daemon is non-critical from the guest OS's
perspective, however, it is used by the Hyper-V host to exchange
information with the guest OS instance, such as IP addressing and system
state information. When not running various information usually
accessible to the hypervisor won't be which can impact scripting tasks
as well as in some cases system functions (e.g. some backup types may be
affected where they rely on the daemon to communicate with the host).
