Unlinking a file or directory and renaming a file all result in a
symlink whiteout, it's just renaming a file that does the wrong thing.

Hi,
this is an Ubuntu-specific bug, the overlayfs v1 compat patch is not
included upstream.
(For completeness, I did boot the 3.19-rc4 mainline kernel and verify
that, per comment 4.)
FWIW, I think (but am not sure how to confirm) that it's falling into
vfs_rename with flags including RENAME_WHI
This is fixed in utopic and later.

Any information about the physical host running the L1 guest?

Having posted, I see that this is actually a utopic kernel that oopsed
(3.16.0-71-generic)
However, the oops stack is still possible on trusty, the blk-merge code in
3.13 doesn't include the fix
that appears in the vivid kernel.

Evolution is the application that Ubuntu uses for calendar, mail, and
contacts. A similar program would be Mozilla's Thunderbird.
It doesn't surprise me that removing it would free up some RAM, but I
don't think this is necessarily the root of the problem. Removing it
from other versions of Ubuntu
The bug is only semi-fixed upstream. With kernels 4.4.0-36 and 38 there
is still a bug but it is different than what I originally reported.
With these two kernels, I can boot up the system and even log in, but
once I log in my home directory appears to be empty. I imagine this is
