No, I didnt see any error message on the screen...
Following are the observation...
1. When I fire command New-VM, it took about 40 sec to start new vm activity on Vcenter/ESX
2. Time took for VM creation is near about 2-3 min with New-vm command where as it took less than 1 min if I do it manually through VCentetr. So in short it took (2-3)min+40 sec to complete VM creation activity.
Above observations are for two different VM creation from same template (powercli command and manually through VCenter)
