Some isos not booting

[Walter Lapchynski]

tl;dr post-final Beta Lubuntu Vivid fails to boot in virtual machines,
but not Xubuntu

I appended the bug report with a lot of information I've collected
from this thread as well as conversations I've had on IRC and
subscribed some of the key people. If you guys could report any
further findings you have about what does and does not work, that
would be great.

With final release coming next week, we need to move quickly if we
intend to have anything but bare metal testing this time around.

I entreaty all flavors to test themselves!
