For file-backed disk images used for domUs, what is the current
best-practice filesystem to use? That is, the filesystem with the
fewest edge cases and failure modes.

I was told (6 months back or so), to absolutely not use a journalled
filesystem on a file-backed image, and so I started moving to ext2. Is
this advice still pertinent, or would a journalled filesystem now be
better (XFS or ext3, for instance).


I've been using ext3 with little trouble. Ext3 has the advantage of coping, successfully, with 50,000 files in one directory without hiccup-ing, which ext2 always had trouble with.
