lxc image copy should be (at least optionally) more verbose

Hi,

Yes, there are a number of operations for which we used to lack progress information entirely which made this impossible.

Recently, I've implemented the events API and updated most download paths within LXD to expose progress information back to the client (by increment of 10% to avoid flooding them with events), our default client however doesn't yet use this information.

Our focus is currently on a few big and complex features that we want to land before feature freeze (remainder of resource limits and native simplestream support) but I'm hopeful we'll get some time to fix some of those rough edges in the command line client in time for 16.04.

I tried to fix this one during one of my flights today but it turns out that on local transfer, we're going so fast that no progress events even get emitted (whole thing is downloaded within 1s) and trying from an airport lounge, internet is so slow (Johannesburg airport) that I'd have to wait about 20 minutes for the damn thing to download :)

Will try again later this week when I've got faster internet.

Found a way to simulate what I needed on my last flight of the day, fix for this bug has been submitted upstream.

This bug was fixed in the package lxd - 0.27-0ubuntu1
