Actutally i tried with all ESXi 5.1, 5.5 and 6.0..
None of them would work..
Anyway i tried a fresh install of the esxi6.0 and checked the VM folder..I am attaching the same for reference. There is no field labelled as ethernet#.virtualDev so am confused.
I am also sending few screen shots during the installation..
There is a message saying no nsf4client found.. then it goes to no network drivers found..
