Robert Larson posted a note for people to be aware of if testing Hyper-V R2 out on lab machines. Your machine may only have one NIC which is contrary to MS’s recommendations:
- 1 NIC for the parent partition
- 1 NIC for virtual machine networking
- 1 NIC for heartbeat (if using clustered hosts)
The default configuration for Hyper-V R2 is that the NIC assigned to the parent partition cannot be used by virtual networks, i.e. child partitions. There is a tick box in the virtual network configuration that you can use to allow the NIC to be shared by the parent and child partitions. Robert has posted a screenshot.
Important has 1nic for Live Migration, correct?
Yes, if you are doing Live Migration in production and want the best configuration possible.
