** [tickets:#2514] plm: handle race condition for EE instantiation between host 
and VM when VM is controller**

**Status:** accepted
**Milestone:** 5.17.08

If the controller is a VM, we have a parent/child relationship like 
safEE=Controller,safEE=Host,safHE=hardware,safDomain=plmDomain

In this case plmcd is running on both the host and VM, but plmd is only running 
in the VM. A race condition exists here as to which plmcd request is handled 
first: the host or the controller VM. If the host comes in first everything is 
OK. But, if the VM comes in first, PLM will think that the host EE has not 
instantiated yet, and will shutdown the VM! Now we are stuck!
