Zmiana typu interfejsu w VMware Workstation

W większości niestandardowych systemów takich jak np. FreeNAS VMware Workstation przy tworzeniu maszyny tworzy interfejs(y) sieciowe wykorzystując domyślnie sterownik e1000, który pozwala na wyciągnięcie 1 Gbit/s po stworzeniu sieci pomiędzy maszynami wirtualnymi/hostem. To jest problem, bo czasami jeśli chce się zrobić testy na iSCSI, sprzęt mamy wydajny i coś wolno działa. Generalnie ten sterownik jest problemem i jest proste rozwiązanie na zmianę tego sterownika na wydajny vmxnet3, który pozwala na wyciągnięcie na luzie 10 Gbit/s. Problem w tym, że nie każdy system to wspiera. W moim przypadku wiem, że wspiera.

Rozwiązanie jest proste: wystarczy znaleźć plik o formacie *.vmx dla naszej maszyny wirtualnej (w moim przypadku jest to maszyna freenas.vmx, edytować plik i zmienić zmienną ethernetX.virtualDev = "e1000" (X – numer interfejsu sieciowego) na ethernetX.virtualDev = "vmxnet3". To załatwia sprawę, ale trzeba pamiętać, że system wykryje te interfejsy jako nowe przechowując nadal starą konfigurację, więc trzeba się upewnić, że nie ma się w swoim systemie przypisanych żadnych ustawień do tych „starych” interfejsów.
