It seems to be the same problem that I have with OpenBSD 4.5 [1]. I did
not test with Virtio because I don't know if OBSD kernel supports it.
Testing with the default network interface and the same kernel compiled
(with disabled mpbios device) I have the same problem.

When I was using KVM-62, I was using the ne2k_pci driver with stock
kernel and this configuration worked without problems. But this
configuration stopped working with KVM-88 and, under these
circumstances, mbios disabled and e1000 gave good results for me.

Backing to use the ne2k_pci driver with mpbios disabled, the network is
reachable again. I will to try with stock kernel and I will comment the
results.

In my case it is Linux 2.6.32 with qemu-kvm-0.12.0-rc2.

In this case I'm using Ubuntu Hardy Heron amd64 on the host and OpenBSD
4.5 i386 on guest.
