How to fetch VM IP address from SCVMM using powershell

$VM = Get-SCVirtualMachine -Name "VMname"

$ValuesMap = @{}

$ValuesMap.Add("NetworkAddressIPv4", $null)

$map=Read-SCGuestInfo -VM $VM -KvpMap $ValuesMap

$map.KvpMap.NetworkAddressIPv4

UPD: another cmdlet that give IP specific info is Get-SCIPAddress, but KVP is more flexible if you also need other VM information from Integration services channel.
