Hi David,
if it turns out to stay reproducible enough I can certainly try somewhen
next week.

Will do so along my checks if it triggers reliably enough for a bisect.

No explicit bandwith limit set, the connection itself is only virtual
(migrating two libvirt/qemu stacks in between lxd containers) so other than
networking overhead this is usually really fast.
I quickly sniffed with iperf on a few of the test hosts and speed was
around 30-120 GBit/s which should qualify as "fast enough".
I'll get back to you once I found the time to verify reproducibility and
hopefully a bisect.
I beg your pardon as this might need a few days (to free up my tasks as
well a system capable to do so).
