Dynamic Switch Ports By default, every vSwitch is placed in the default Primordial pool for the Ethernet resource pool Dynamic Switch Port functionality allows a VM to request to connect to one or more virtual switches in a poll of virtual switches Primordial pool vEthernet (Public)vEthernet (DMZ) Public poolDMZ pool vEthernet (Public)vEthernet (DMZ) Resource pool configuration using PowerShell (New-VMResourcePool) Two-part process 1. Create the Ethernet resource pool 2. Add the vSwitch to the resource pool Note: Properly configured Ethernet resource pools on Hyper-V hosts should allow for a proper automatic connection when a VM migrates because the virtual machine network configuration is now part of the virtual machine configuration Server Virtualization Hyper-V 2012
