Hi Barry,
thanks for your report.
Several questions trying to get us analyzing this:
1. how (fast) reproducible is this?
2. you say heavy network load through to ceph, did you ever reproduce without
ceph (like any network benchmark tool? - that would ease reproducing this).
Also even if ceph only, do you have any numbers in #packets, sizes, throughput
along that.
I don't know if iptraf still works, but might be worth a try to gather some
info what/how much load it is.
3. the referred bug report initially was about e1000 devices in the
guest, what do you have (virtio as usually?)
4. I bet you'd have said so, but just in case anything in the logs
(var/lib/libvirt/qemu/<guest>.log?
