You're setting this feature twice. > + add_feature(dev, VIRTIO_NET_F_GUEST_CSUM); You set this feature, but I never see the virtio-net driver acknowledge the feature. Curiously, my implementation with KVM is struggling because UDP packet checksums are not correct so the DHCP client is ignoring them. If I disable CSUM offload, things it works fine (using the virtio-net header). The problem is only host=>guest, guest=>host is fine.
