Hyper-V host crashes and has bug checks when you perform a VM live migration in Windows 8.1 and Windows Server 2012 R2

Microsoft has released the most important KB for Hyper-V related with VMQ,LBFO and LM

Consider the following scenario:

  • You have a Windows Server 2012 R2-based computer that is configured for one or more NIC teams by using Windows NIC Teaming (LBFO).
  • You have implemented Windows NIC Teaming (LBFO) in Switch Independent teaming mode by using Hyper-V Port or Dynamic Load Balancing mode. Additionally, you have correctly configured the NICs to use non-overlapping processors. (For more information, see Knowledge Base article 2974384).
  • A Hyper-V virtual switch is bound to one of the LBFO teams.
  • You start a virtual machine on the Hyper-V server, or you live migrate a virtual machine from one server to another server.

In this scenario, you experience one or more of the following issues:
