dhcp-server 3.0.4. And DHCP works fine from an installed guest domain.
And as stated in my initial message, I see response packet arriving on
the bridged interface (xenbr0), as well as on the guest domain virtual
interface (vif13.0 in the given capture file). Hence my assumption than
network setup and server is OK, and problem comes from emulated network
card.
As a potential issue, dhcp reply comes from another network, through a
proxy. I once had troubles with windows client ignoring those answers if
their origin was not strictly set to the local network broadcast adress.
