We are still playing around with this in the lab...

Running similar setup as the customer
 Microsoft Windows Server 2012 R2 Datacentre (6.3.9600) Revision 16384
 Hyper-V 2012

Two VM guests
 - 11.0-RELEASE
 - 11.1-p1

We can not get the Hyper-V hn interface to lock up like the customer can
though.

We can get the VMs to hang/stall regularly if the guests run ntpd - approx
every 15 mins, but no real obvious pattern to it.  Disabling ntpd fixes it.
