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

Disabling the Checksum Offloading the following way on Your Windows PC solved the Problem.

1. Click Start - Search and type “regedit”.

2. Go to the following registry key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters

HKEY_LOCAL_MACHINE
\SYSTEM
\CurrentControlSet
\Services
\Tcpip
\Parameters

3. Add a DWORD(32bit) Value named "DisableTaskOffload" and set it to "1".
4. 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:
