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.
