Windows Server 2016 HyperV - SuSe SLES12 SP2 Guest machine's network adapter settings not aligned with windows host RRS feed

  • Question

  • Hi,

    My Windows server 2016 HyperV SuSe Guest SLES12 SP2 machine's network adapter settings are not aligned with the physical network adapter settings in windows server 2016 host, i.e.  in hyperv SuSe SLES12  guest machine is showing "Unknown" Duplex and Auto-negotiation=off, but in windows server 2016 host, the physical adapter is showing Full duplex mode and auto negotiation is ON.   Is there a way to make these two network settings parameters in SuSe HyperV guest machine align with windows Host  network adapter settings ?
