Hi,
We have a requirement in Boxes for showing progress bars on VMs under installation:
https://github.com/gnome-design-team/gnome-mockups/raw/master/boxes/boxes-in... https://bugzilla.gnome.org/show_bug.cgi?id=679107
However, we are bit clueless on how that could be achieved. The only idea I have is to know the number of passes (reboots) and typical disk usage in each pass for "every" (we only do this for express installs so we don't need this for all) OS and estimate the progress based on that knowledge. If that idea is worth looking into, we'll need this information in libosinfo and hence me cross-posting this to virt-tools-list.
Other ideas welcome! Keep in mind that we don't need to be very accurate, just accurate enough to not annoy the user.
I don't see any general purpose way todo a progress feedback. The best you can do is to show whether /something/ is happening (by looking at disk & net I/O stats). If you want actual progress feedback then you're looking at modifying the guest OS init process / installer to send feedback over a virtio-serial device directly, or indirectly via a guest agent.
