This is shown by error: "KVP: read failed; error:9 Bad file descriptor" I then manually ran the kvp binary, it returned the KVP data, and it's also automatically loading at boot. However, this is of course not the normal behavior. 17.04 daily from Febr 14th is the first build we covered, so I cannot say if this is a regression introduced only at some point in 17.04 dailies. In syslog these are the only messages for KVP: Feb 14 08:01:22 ubuntu systemd[1]: Started Hyper-V KVP Protocol Daemon.
