Best lessons learnt while moving part of my LAB from Virtual Server 2005 R2 to Windows Server 2008 R2 Hyper-V

Issue: Laptop Wireless NIC is not available by default to VM’s in Hyper-V 🙁


  • In Hyper-V Virtual Network Manager, create a new ‘Internal Only’ NIC e.g. Virtual Wireless Network
  • In Windows Server 2008 R2 Network Connections, create a bridge between the Wireless Network Connection and the Virtual Wireless Network.
  • Add a NIC and connect it to the Virtual Wireless Network for a VM in its Settings

Issue: Migrating VM’s from Virtual Server to Hyper-V result in no mouse integration, no network adapter and a ‘VMBus’ device that cannot be installed (i.e. Yellow exclamation mark in Device Manager) 🙁


  • Uninstall old virtual server integration components
  • Restart VM
  • Install new Hyper-V integration services
  • Run msconfig.exe, Boot, Advanced Options, Detect HAL, Enable
  • Restart VM
  • Run msconfig.exe, Boot, Advanced Options, Detect HAL, Disable
  • Restart VM
