Xenial builds occasionally fail when using LXD as a Snap

Hello -

We are using TravisCI to build and publish Snaps and I encountered an issue yesterday with Bionic where the build would hang at sudo lxd.migrate -yes for quite some time, sometimes 5+ minutes, and occasionally cause the build to fail due to a time out.

We are using LXD to build our Snaps using the LXD from the Snapstore itself since it always has the latest stable version.

This does not happen on the Xenial image - only the Bionic image.

Is this a known issue or something we can report as a bug?
