Correct. That site is sort of

the guest does not crash and maintains network connectivity throughout
the test.

I believe that we have identified a regression in qemu-kvm-0.11.0.
The kvm process crashes for older guests with virtio networking, when
the guest's incoming network connection is saturated. The subject

You might, perhaps, try kvm-84, which is more current and fixes a
