Hi Chris, Thanks for investigating. I've tried again to confirm the problem still occurs -- and it does, although sometimes it takes multiple restarts of the hv-kvp-daemon.service for it to start successfully.
Some diagnostic information is below. Welcome to Ubuntu 16.04.2 LTS (GNU/Linux 4.4.0-62-generic x86_64) user@server:~$ ps -ax | grep hv 129 ? S< 0:00 [hv_vmbus_con] 359 ? S 0:00 [hv_balloon] 601 ?
