virt-top is 'top' for virtual machines. Tiny program with many
powerful monitoring features, net stats, disk stats, logging, etc.

Subject: [PATCH] appliance: Add support for btrfs, GFS, GFS2, JFS, HFS, HFS+, NILFS, OCFS2
However don't enable OCFS2 by default, because it pulls in about
140 extra packages into the appliance.
GFS & GFS2 default to single node (no lock manager etc).
