Vagrant users are accustomed to much larger disk sizes so lets give it
to them. I'm leaving the others as-is since it is easier to grow than
shrink disks if anyone has a particular size they need.
Use the smaller base format for 'raw' disk images since these will
usually be dd'd to a block device to create AMIs and what not. For
images using qcow2 and vmdk stick with the larger vm size.
This change removes /usr/sbin/write_gpt.sh from images which we have no
use for. This allows us to drop the indirection of writing partition
tables by first writing out a script to call. Now cgpt.py can call cgpt
directly to initialize the partition layout. This opens the way for
further improvements to how disk images are created.
This one is more automagical and sets up ssh keys from ssh-agent and the
user's home directory by default. Also adds an option for setting the
ssh port so it can be something other than 2222. Script should be
sufficiently portable, tested in bash, dash, and ash.
The recommended command using the config file was triggering a massive
memory leak in qemu because it was adding both the default virtual
hardware nic as well as the virtio nic. This could be worked around by
adding something like -net none or moving all the -net commands from the
file to the command line but eh. Clearly qemu config files are used and
tested by nobody else so lets just use a trusty script instead.
Vagrant will need the virtualbox ovf plus its own Vagrantfile config.
After this we will need an optional "package" step to this script to
take these files and bundle them into a .box tarball. This could also be
used to switch from .ovf+vmdk for plain virtualbox images to a bundled
.ova archive which combines the two.
Trying to include version info by adding the directory name to VM image
names didn't work and a better solution is for build_image to write out
a version.txt file. This should also fix an issue where uploading from
image_to_vm.sh didn't always go to the same location as the images
uploaded from build_image did.
Enable sparse files for all dd and cp commands and replace some dd
commands that are really better off being truncate commands.
While in the neighborhood there were a number of useless sudo commands
for things that just happen to be in sbin. Call them directly instead.
Last minute bug slipped in because of a line I commented out since the
current coreos kernel doesn't support virtio block devices (that change
coming soon). Qemu doesn't tolerate any spaces before # in comments.
The old script was heading towards spaghetti code realm. This breaks up
all the image variations such as hybrid MBR, OEM packages, etc into
configuration options and small functions that actually do the work.
All this is in the new vm_image_util.sh library but the command line
parsing and overall procedure remains in image_to_vm.sh
As part of this we gain support for putting some qemu options in a
config file as well as Xen virtual machines using pygrub and pvgrub.
Lots of generally unused options have been removed to simplify things
and keep output file names consistent.
