Problem has been identified and solution will be put in place today which will require a reboot of the VMs but it takes just a few seconds so I don't think you'll notice it.

It was the generic-segmentation-offload in virtio_net driver for the guests that caused IPv6 to be very slow when sending, you'd get a burst of ~450KB then it would drop down to 15KB/s.
