Some friends here on the Hyper-V team shared a PowerShell 2.0 script for connecting your virtual switches to the management partition (parent partition):
# Connect a Virtual Switch to the management partition param( [string]$vsName = $(throw "Must specify virtual switch name"), [string]$intEthName = [guid]::NewGuid().guid, [string]$switchPortName = [guid]::NewGuid().guid ) $vSwitch = gwmi -namespace root\virtualization Msvm_VirtualSwitch -filter "ElementName = '$vsName'" $vsms = gwmi -namespace root\virtualization Msvm_VirtualSwitchManagementService # Create a new internal ethernet port $result = $vsms.CreateInternalEthernetPortDynamicMac($intEthName,"Internal Ethernet Port") if($result.ReturnValue -ne 0){ return $result.ReturnValue } $intEthernet = [wmi]$result.CreatedInternalEthernetPort # Create a new switch port on the virtual switch $result = $vsms.CreateSwitchPort($vSwitch, $switchPortName, "Switch Port to Internal Ethernet", "") if($result.ReturnValue -ne 0){ return $result.ReturnValue } $switchPort = [wmi]$result.CreatedSwitchPort # Get the endpoint connected to the internal ethernet port and # connect it to the switch port $endpoint = gwmi -namespace root\virtualization ` -query "Associators of {$intEthernet} where ResultClass = Msvm_SwitchLANEndpoint" $result = $vsms.ConnectSwitchPort($switchPort, $endpoint) if($result.ReturnValue -eq 4096){ # A Job was started, and can be tracked using its Msvm_Job instance $job = [wmi]$result.Job # Wait for job to finish while($job.jobstate -lt 7){$job.get()} # Return the Job's error code return $job.ErrorCode } # Otherwise, the method completed return $result.ReturnValue
# Connect a Virtual Switch to the management partition
param( [string]$vsName = $(throw "Must specify virtual switch name"), [string]$intEthName = [guid]::NewGuid().guid, [string]$switchPortName = [guid]::NewGuid().guid )
$vSwitch = gwmi -namespace root\virtualization Msvm_VirtualSwitch -filter "ElementName = '$vsName'" $vsms = gwmi -namespace root\virtualization Msvm_VirtualSwitchManagementService
# Create a new internal ethernet port $result = $vsms.CreateInternalEthernetPortDynamicMac($intEthName,"Internal Ethernet Port") if($result.ReturnValue -ne 0){ return $result.ReturnValue } $intEthernet = [wmi]$result.CreatedInternalEthernetPort
# Create a new switch port on the virtual switch $result = $vsms.CreateSwitchPort($vSwitch, $switchPortName, "Switch Port to Internal Ethernet", "") if($result.ReturnValue -ne 0){ return $result.ReturnValue } $switchPort = [wmi]$result.CreatedSwitchPort
# Get the endpoint connected to the internal ethernet port and # connect it to the switch port $endpoint = gwmi -namespace root\virtualization ` -query "Associators of {$intEthernet} where ResultClass = Msvm_SwitchLANEndpoint"
$result = $vsms.ConnectSwitchPort($switchPort, $endpoint)
if($result.ReturnValue -eq 4096){ # A Job was started, and can be tracked using its Msvm_Job instance $job = [wmi]$result.Job # Wait for job to finish while($job.jobstate -lt 7){$job.get()} # Return the Job's error code return $job.ErrorCode } # Otherwise, the method completed return $result.ReturnValue
