A: No, when you use Virtual Fibre Channel in Hyper-V, the Hyper-V host doesn't have to be zoned. Virtual Fibre Channel adapters are added to virtual machines (VMs) and each Virtual Fibre Channel adapter has its own unique World Wide Port Name (WWPN) (as documented at the TechNet article "Hyper-V Virtual Fibre Channel Overview."
The WWPN of the Virtual Fibre Channel adapter has to be zoned and given access to the storage. The Hyper-V host itself doesn't require any access, making this a very secure solution that differs from other virtualizaiton platforms where the host itself requires full access to any storage a VM needs access to.
You will notice that each Virtual Fibre Channel adapter actually has two WWPNs. This is so that when a VM is moved between hosts, the VM running on the target host can use the second WWPN when it starts on the second host, avoiding the need to move the WWPN between adapters, which could cause a pause in connectivity.
