Title:
  [Hyper-V] lis daemons not active after install on  Ubuntu 15.10 Wily
  Werewolf

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Wily:
  Confirmed

Bug description:
  While testing Ubuntu 15.10 Wily Werewolf (development branch) 64bit we
  found that kvp, vss and fcopy daemons aren't active after install.

  Repro rate: 100%
  Repro details:
  Hyper-V: Server 2012 R2
  Daily build version: 2015.08.31

  What we did: 
  root@ubuntu:~# apt-get install linux-tools-`uname -r`
  root@ubuntu:~# apt-get install linux-cloud-tools-`uname -r`

  
  In the install logs I found the following lines:

  hv-fcopy-daemon.service is a disabled or a static unit, not starting it.
  hv-vss-daemon.service is a disabled or a static unit, not starting it.
  hv-kvp-daemon.service is a disabled or a static unit, not starting it.

  
  After reboot, the kvp, vss and fcopy daemons should have started. All of them are inactive (dead) instead.

  root@ubuntu:~# systemctl status hv-kvp-daemon.service
  ? hv-kvp-daemon.service - Hyper-V KVP Protocol Daemon
     Loaded: loaded (/lib/systemd/system/hv-kvp-daemon.service; disabled; vendor preset: enabled)
     Active: inactive (dead)

  
  The solution is to start each of them manually. The bellow applies to vss and fcopy daemons too.

  root@ubuntu:~# systemctl enable hv-kvp-daemon.service
  Created symlink from /etc/systemd/system/multi-user.target.wants/hv-kvp-daemon.service to /lib/systemd/system/hv-kvp-daemon.service.

  
  After reboot, the daemons are active.

  root@ubuntu:~# systemctl status hv-kvp-daemon.service
  ? hv-kvp-daemon.service - Hyper-V KVP Protocol Daemon
     Loaded: loaded (/lib/systemd/system/hv-kvp-daemon.service; enabled; vendor preset: enabled)
     Active: active (running) since Mon 2015-08-31 15:22:49 EEST; 23s ago
   Main PID: 899 (hv_kvp_daemon)
