I have one NIC on the machine loaded XP on the Hyper-V and had chosen the network as virtual switch. No LAN and no internet shows up on the client. Am I missing something? it used to work in 2008-R2.

Details:

  • One network card on machine (Qualcomm Atheros AR8131 PIC-E Gigabit Ethernet controller)
  • The virtual machine hard disk is pointing to and existing XP-SP2 hard disk created using VPC 2007
  • The Virtual machine Network Adapter is setup as Virtual Switch to the real ethernet controller with Enable virtual LAN identification set to 2 (no other virtual machine is created in the system)

After the virtual machine boots LAN shows empty in Control Panel > Network Connections (this is XP client) and I also cannot access the internet. XP is showing activation prompt but as far as I know it should not disable the network!

Virtual network switch is set to External
