gnome-shell cpu usage during installation

[John Reiser]

> If I try to do this in KVM (2x CPU), I see gnome-shell taking 5%, X not even displayed in top, and all CPU power going to rsync (2x 10%) and loop3 (80%).

Please tell us how much virtual RAM was allocated to the KVM instance.
loop3 at 80% CPU for long periods is page thrashing: re-decompressing
parts of the ".exe" over and over because the resulting pages
are discarded too quickly.
