If you have problem with Win7 or Win2012 KVM guest with dhcp not working, you can try to disable checksum offloading

  • Click Start - Search and type “regedit”.
  • Go to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

  • Add a DWORD(32bit) Value named "DisableTaskOffload" and set it to "1".
  • Restart the Windows PC to make the changes happen.

Custom NIC Checksum Settings

If you need to set NIC checksum only for IPv4/Pv6, TCP/UDP, RX/TX you can use the NIC Advanced setting here:
