i faced this issue i don't know Why the adapter that is deleted from vm is back after the vm reboot? can anyone help me to understand this? and how to resolve this issue?
Are you talking about the VM's settings, or do you see the adapter in the guest OS although it doesn't exist in the VM's settings anymore?
Which guest OS do you use?
i am talking about vm settings
So what you are saying is that you delete the network adapter from the VM's hardware settings, and after rebooting the VM it's listed again? That's indeed unusual and the only reason that I can think of is that the VM is reverted to a snapshot!?
no it's appearing automatically and vm has no snapshot
The only idea that comes in mind is that there might be an issue with the ".vmx"/".vmx~" files (see http://www.virtuallyghetto.com/2013/02/why-are-there-two-vmx-files.html), i.e. with properly updating the VM's configuration (.vmx file). However that's more guessing than knowing.
