SCVMM – Change VM NIC from Static to Dynamic IP

Just a quick post to document how to make a change with System Center Virtual Machine Manager.

I have a VM with a NIC attached to a VM Network that has a Static IP Pool. For a few not-so-great reasons, I need to remove it from that pool back to a Dynamic IP address.

In the GUI, this option is disabled:

Here’s how to accomplish it with PowerShell:

# Get the virtual machine into an object
$vm = Get-SCVirtualMachine -Name "VMNAME"

# Find the destination VM Network you want to change to (the one without the Static IP Pool)
$vmnetwork = Get-SCVMNetwork -name "VMNETWORKNAME"

# Find the VM Subnet on the VM Network
$vmsubnet = Get-SCVMSubnet -VMNetwork $vmnetwork #Assume single subnet

# Using the pipe to find the NIC (assume single NIC), modify the properties to Dynamic
$vm | Get-SCVirtualNetworkAdapter | Set-SCVirtualNetworkAdapter -IPv4AddressType Dynamic -vmsubnet $vmsubnet
