add VM descriptions to OVF
fix truncation of image name in grub
fix Makefile to rebuild box when .vmdk changes
allow overridding TMPFS_SIZE
allow disabling use of tmpfs via NO_TMPFS=1

Despite significantly reducing the build time, tmpfs does
seem prone to kernel bugs, so better make it optional.
eliminate duplication between box creation Makefiles
add main() to allow full refactoring
eliminate duplication between build-image.sh files
rename admin node image name in grub for clarity
switch from IDE to SCSI disks and add DRBD
generate config.xml from template

This allows us to eliminate hardcoding of paths within config.xml.
make DRBD disk larger and first

It needs to be at least 2GB since database and rabbit both need 1GB
until we support floating sizes.  It needs to be first because the
disk claiming code isn't particularly cunning yet.
set up glance shared mount
drop cinder shared disk

For this to work in the cluster we'd need cLVM; simpler to keep on the
compute node for now.
use vbox:OSType Linux not Linux_64

Linux_64 is not supported on VirtualBox 4.2, and 4.3 seems fine
with Linux.
scrap pointless 45 second tcpdump per interface

This is only useful on networks with LLDP.
ensure glance shared disk is ext3
remove comment which doesn't apply to sles11-sp3 image
fix ordering of sudo package
ditch SLE-11-SP3-SDK-Updates

None of the packages we get from SDK have updates (and even if they
do later, we probably don't need them).
