We have an 11 node Hyper-V cluster running Server 2012 R2 with all latest updates.
We have had an ongoing issue with nodes BSODing or hanging.
Specs:
Hyper-V Nodes-
128-256GB of RAM per node, depending on generation. 12-32 cores. None of the machines are starving for resources. We have a cluster setup through SC VMM 2012 R2 that optimizes the VMs every 30 minutes. The vhd's for VM's sit in a SMB 3.0 share hosted by a SOFS cluster w/ Storage Spaces on a JBOD. Each Hyper-V host utilizes 2 x10Gb Intel NIC cards (either X520-T2 or X540-T2 depending on node) in a NIC team that is currently set to active-standy
We have tried:
adjusting VMQ settings so each NIC uses different cores
Switching NIC team from Active-Active to Active-Standby.
