Last week I decided to bite the bullet and upgrade from Ubuntu 10.04 to a more recent version. I downloaded an upgrade to 12.04, and then used that to do an online upgrade to 14.04. As a result of this, I lost most of the applications needed to build LilyPond. I've grabbed a number of then with
the software installer or apt, but gave that up for a while whilst I
needed the machine for another purpose.

I would first try to set up the system and avoid virtual machines for LilyPond development.
Installing the dependencies should be as easy as:

sudo apt-get build-dep lilypond

Except when it isn't.

I.e. all those extra bits that are documented in the CG.

I did a bit of work on a number of Distributions and have had to document those little idiosyncrasies there.

If/When something breaks, you might consider the virtual machine.

This was to run a Windows 7 VM - I use this with Adobe Lightroom 6 (which won't run on my Vista desktop) for editing my photos. So I installed the
latest Oracle VirtualBox and discovered that 14.04 mounts its disks in
media/username, meaning that VB could not find the image of my VM.  I
hacked the set up file by hand, and got the VM running.  Problem is, it
runs like a complete drain, taking about two minutes to move between
photos.  The VM on 10.04 was instantaneous.  No idea why this should be,
but I got so p**sed of with it that I've ordered a new PC just for my

I would have tried another virtual machine (libvirt and virt-viewer work great) and/or another guest.

By the way, do you know Darktable?

I think that it's very similar to Lightroom, but it's open source and runs on Linux and Mac.
It works very well and it's actively developed.

So I'm back to thinking about what to do with the Linux installation. An option would be to start from scratch with the latest version of LilyDev.
My concern is how this would mount my two non-system disks: a 2TB hard
drive and an SSD.  With 14.04, if I access my SSD from my "patchy" user,
my mail "phil" uer can't see the drive since it seems to mount at

I don't understand clearly what's your setup, but at work I'm using Samba to share folders between Linux guest and Windows 7 host.
You cannot assign a 'Physical Disk Device' (i.e. one that is being used by the Host OS) directly to a VM as the same Disk Device (at least in Virtual Box), but you can share a folder(s) on that Disk as Federico says - in my case I share a folder from my Linux Host to a Windows VM.

The 'folder sharing' feature in Virtual Box is much nicer than the other Virtualization platforms I think and the Windows VM sharing a Linux Host Directory is easier than the other way round frankly. less complicated to set up, but the Help that comes with Virtual box explains this.
