Q. Can I use the management NIC for a cluster network? I only have two NICs in my Hyper-V host.

A. You can, but it isn't an ideal situation. Normally, the cluster network isn't routed and is dedicated to only Cluster Shared Volumes (CSV) and cluster traffic. If you're restricted to only two NICs, using the management NIC for cluster traffic would work, especially if you think management traffic is likely to be minimal. Virtual LANs are one option to separate your traffic into virtual networks across the single physical NIC, depending on your environment.

• Q. If I have multiple physical network cards associated with different virtual switches in my Hyper-V cluster, how does Hyper-V know which virtual switch to map the virtual NIC to during a node move?
• Q. What's the relationship between a virtual switch and a physical NIC? Should each virtual machine (VM) have its own virtual switch?
• Q. Why shouldn't I share the management NIC on Hyper-V with virtual machines (VMs)?
• Q. How can I perform a physical to virtual (P2V) migration with System Center Virtual Machine Manager (SCVMM) 2008?
