[gentoo-user] btrfs and sparse VM image files

[Neil Bothwick]

I'm confused about the desirability of keeping VM image files, usually
space qcow files, on a btrfs volume. I have read the advice about using
chattr +C on the subvolume, but are there any other gotchas? The btrfs
wiki says in one place that using sparse file on btrfs is not a good
idea, but is that still the case. There is conflicting information out
there, does anyone here have any hard experience?
