2) Connect with vsh, create a debian container
3) In the debian container, apt update && apt install gnome-mahjongg

commit 72dd367aa850a505b95744635692419cd1433932
Author: Dylan Reid <dgreid@chromium.org>

qcow: Calculate correct refcount table size and zero it

The reference count table must be continuous in the file, not
preallocating it when creating a file causes errors when setting
reference counts for new blocks later.

BUG= 809847 
TEST=Replay formatting and downloading container events.
Add unit test that catches error with default files.
