Windows 2012 Server Hyper-V: Cannot see LAN

hyper-vwindows-server-2012

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

Ok, so do you expect the traffic to be tagged with VLAN ID 2? If not, why do you consider it necessary to set a VLAN id? Did you make sure the Ethernet Card is handling and Pasing through tagged traffic? Some do not without reconfiguring.
