Maybe it fast-pathes around something when both are virtio. But you said you set driver=qemu and it still was broken with virtio, I didn't expect that.
I have given it a few tries with a similar setup among a few VMs but haven't seen the issue myself. You probably want to report that upstream to get more eyes/brains onto that case. But with the case as-is atm I'm not really sure if that would be better started at libvirt [1] or qemu [2]. Maybe start with one and if redirected from there go to the other? I'm subscribed on both, but would appreciate if you could add here a link to the thread you started on the ML to find it again later.
