Some friends here on the Hyper-V team shared a PowerShell 2.0 script for getting a custom KVPS:
# Get Custom KVPs param( [string]$vmName = $(throw "Must specify virtual machine name") ) $vm = gwmi -namespace root\virtualization Msvm_ComputerSystem -filter "ElementName='$vmName'" # Get the associated KVP Exchange component $kvp = gwmi -namespace root\virtualization ` -query "Associators of {$vm} where ResultClass=Msvm_KvpExchangeComponent" # Pull the Guest Exchange Items from XML into a hash $kvpHash = @{} if($kvp.GuestExchangeItems){ ([xml]("<xml>"+$kvp.GuestExchangeItems+"</xml>")).xml.instance | ` foreach{$kvphash.add($_.property[4].value,$_.property[1].value)} } return $kvpHash
# Get Custom KVPs
param( [string]$vmName = $(throw "Must specify virtual machine name") )
$vm = gwmi -namespace root\virtualization Msvm_ComputerSystem -filter "ElementName='$vmName'"
# Get the associated KVP Exchange component $kvp = gwmi -namespace root\virtualization ` -query "Associators of {$vm} where ResultClass=Msvm_KvpExchangeComponent"
# Pull the Guest Exchange Items from XML into a hash $kvpHash = @{} if($kvp.GuestExchangeItems){ ([xml]("<xml>"+$kvp.GuestExchangeItems+"</xml>")).xml.instance | ` foreach{$kvphash.add($_.property[4].value,$_.property[1].value)} } return $kvpHash
