Hello Wila! appreciate a lot your answer.
Notice:
There is no issue after suspend/resume the guest VMs. Conectivity from host to them works good after that event.
The problem is when the host is suspend/resume. Does not matter if the guests are up and running or stopped, in both escenarios they will not be pingable after host suspend (or shutdown)
After restore default in VNE some scripts run that enable back this connectivity.
No need to do any change in VM (either CentOS or Win7) they start working after workaround, and fail after host is suspended.
