pulling values from VM object

Hi, I'm trying to pull a few values from a provisioned VM using a vRO script and I haven't come across anything useful in the API Explorer yet.  Values needed are:  Deployed Time, ESX Cluster and Public VLAN.  Can anyone help with the calls needed to pull this info?  I'm assuming it comes out of the VC:VirtualMachine object, but not sure where it lives.

Thanks,

Scott
