NICs kann man im virtuellen Windows entfernen!

Problem: NICs and SCSI controllers appear as removable devices. The Safely Remove Hardware option for the virtual hardware appears in the Windows System Tray. If you are using VMware View, you notice that View desktops which have persistent disks are disconnecting.

Resolution: You can disable HotPlug capability using the vSphere Client or by editing the .vmx file. Note: You can disable HotPlug capability for PCI devices such as e1000 or vmxnet2 NICs. To disable HotPlug capability using the vSphere Client:
Connect to the ESXi/ESX host or vCenter Server using the vSphere Client.
Power off the virtual machine.
Right-click the virtual machine and click Edit Settings.
Click the Options tab. Click General > Configuration Parameters > Add Row.
Insert a new row with the name devices.hotplug and a value of false
Power on the virtual machine.
