Ok this looks a lot like a video card detection race condition which should drop us into fallback, which seems to be broken currently. @Elfy could you test with the attached file installed in /etc/init/udev-fallback-graphics.conf and let me know (here) if that gets you to lightdm.

Yep - that got lightdm started - logged in to desktop fine.

Ok based on that confirmation I am shoving this over to systemd (which contains udev). This is basically fallout from removing this file to try and fix LP#1367241, reinstating this file with the fix used for SRU to the LTSs for that bug seems to fix it for the reporter here.

Thanks Andy! I'm taking over from here and revert the original removal and replace it with the || true solution that was done in the SRU (I'm glad my paranoia was appropriate in that case :) ) and in your attachment.

I just saw that you already uploaded. I adjusted the packaging git to your upload.

This bug was fixed in the package systemd - 208-8ubuntu6

---------------
systemd (208-8ubuntu6) utopic; urgency=medium

  * Reinstate udev-fallback-graphics.conf without which we will
    no longer start a display manager unless we have a primary
    graphics device. This leads to no display manager on some vbox
    instances and some binary drivers. Note that this version of
    the job also includes the fix used in the LTS SRUs for LP#1367241
    which initially removed this file. (LP: #1375805, #1367241)

Bah that is not being installed correctly, and my test system has an old conf file linkage for that name which made it look like it was in there. Sigh. Will fix and re-upload.

@ apw - always nice to confirm something's working - updated a non-booting install - got the new systemd - boots properly now - thanks

Installed today's daily live (http://cdimage.ubuntu.com/daily-live/20141003/utopic-desktop-i386.iso) in VirtualBox - the bug is really fixed.

But I can't understand why MD5SUM of http://cdimage.ubuntu.com/daily-live/current/utopic-desktop-i386.iso = MD5SUM of http://releases.ubuntu.com/utopic/ubuntu-14.10-beta2-desktop-i386.iso . So the systemd package was updated, but ISO not?
