A key difference that is probably relevant is that netbsd is using an e1000 NIC in QEMU, while openbsd is using a virtio-net NIC. At least when created by virt-manager.
AFAIR, QEMU's magic checksum offload only happens for virtio-net, so presumably our rules are incompatible with non-virtio-net NICs in someway.
Yes, that's it! The GNU/Hurd and Haiku guests are also using e1000, since virtio drivers are not available there; moreover, if I switch a random Linux guest from virtio-net to e1000 I can reproduce the issue there as well. -- Andrea Bolognani / Red Hat / Virtualization
