[libvirt] Tracking VM installations

[Zeeshan Ali (Khattak)]

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-install6.png
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.
