 virtio-kmod with two interfaces drops all packets
Author: glenn

I am trying to set up dummynet between two virtual machines. Using FreeBSD 9.0 as the gateway between the two networks. Hypervisor is KVM running CentOS 6.3

I installed virtio-kmod-9.0-0.242658.tbz from

If I switch the VM to use Intel e1000 NICs then everything behaves as expected, except a little slower than I'd like.

Switching to vtnet0 and vtnet1 allows me to ssh to the VM still, but traffic does not get forwarded between the two networks.

Setting one interface to e1000 and one to virtio behaves the same as with both set to virtio. This is the case regardless of which interface is set to virtio.

Looks like a bug in the networking layer somewhere to me.
