Yup it's a latent bug. Feel free to report a bug and post a patch, but
you're likely building your house on sand because as noted the
libvirt+lxc driver doesn't get integration testing. I used to try to
make a CI job work for that configuration but it was extremely flaky and
it was never sorted out what the underlying issues were (and no one
cared enough to take it up).
