ok, there is no way to get the ip of vm using COM interface directly,
so I use another way...
using "ping computerName" in the cmd.exe to get the vm's ip, hehe
so at first u must know the vm's computerName


try
{
string computerName = CmdArgs[paramIndex];
Process p = new Process();
p.StartInfo.FileName = "cmd.exe";
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardInput = true;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.RedirectStandardError = true;
p.StartInfo.CreateNoWindow = true;
p.Start();
p.StandardInput.WriteLine("ping " +
computerName );
p.StandardInput.WriteLine("exit");
string strOutput =
p.StandardOutput.ReadToEnd();
p.WaitForExit();
p.Close();
if (strOutput.Contains(" with 32 bytes of
data"))
{
int indexStart = strOutput.LastIndexOf('[')
+ 1;
int indexEnd = strOutput.LastIndexOf(']');
string ip = strOutput.Substring(indexStart,
indexEnd - indexStart);
output(ip);
}
else
output("0.0.0.0");
}
catch
{
output("0.0.0.0");
}

please me to find if there is something wrong in the program

ComputerName is a property of the IVMGuestOS object in the virtual
machine object available via the COM interface.

Also you can read any registry key in the GuestOS under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Virtual Machine\Guest\Parameters

If you configure your VMs put the data you want in this registry path
then you can retrieve them via the COM interface with
IVMGuestOS->GetParameter("keyname")

Yes this is specific to your VMs but it works.
