Thanks, that's really helpful.  I'm sure it was mentioned somewhere, but I
was trying different consoles with "root" etc. and unsure on how to get to
the terminal.

So, after initially attempting to just "create" the directory and being
told it was a read-only filesystem, I did a little more investigation and
realized that the "Data" volume (in /dev/HostVG) was simply not mounted.  I
mounted this with the command:

mount /dev/HostVG/Data /data

And now I have a /data/images directory (as well as /data/core).  I'm not
entirely sure why this wasn't mounted since I see it in /etc/fstab.  In
fact, when I discovered it was in /etc/fstab, I tried just

mount /data

And that also worked just fine.  So puzzled that thsi was not mounted when
the system booted up.  Maybe I missed an error message, but dmesg isn't
saying anything obvious (not sure if that's where I'd see mount errors or
not).  Maybe this is a known issue.

Thanks again for the help -- this definitely got me moving in the right
direction.  Hopefully I'm moments away from being able to get that first VM
running.

Thanks,
Hans
