During the installation, you will be asked about the partition scheme. Don’t use LVM partitions. They are not supported by snf-image-creator.
-> Not sure if that applies here.
http://www.synnefo.org/docs/snf-image-creator/latest/usage.html#image-partit...
When image shrinking is enabled, snf-image-creator will shrink the last partition on the disk. If this is a swap partition, it will remove it, save enough information to recreate it during image deployment and shrink the partition that lays just before that. This will make the image smaller which speeds up the deployment process.
During image deployment, the last partition is enlarged to occupy the available space in the VM’s hard disk and a swap partition is added at the end if a SWAP image property is present.
-> Maybe a single / partition and a possible swap space at the end ?

The above docs have to do with the 'snf-image-creator' tool which we use to create our images. After the image is prepared this tool does not get in the path. The image gets deployed and customized by the 'snf-image' tool:
http://www.synnefo.org/docs/snf-image/latest/
However, since snf-image does not operate on LVM partitions, that's why snf-image-creator doesn't support LVM too.
Regarding swap:
The image doesn't need to have a swap partition, since snf-image has a corresponding option to add one dynamically. That's why snf-image-creator removes the swap if it finds it at the end and sets that property accordingly during registration of the image. If the swap is not at the end, it leaves it as is. So, the best thing to do in our case is to *not* have any swap at all in the image.
Thanks, Constantinos
P.S.: snf-image's SWAP property should have been documented here: http://www.synnefo.org/docs/snf-image/latest/interface.html#image-properties... but I just saw it's missing. We'll be patching the docs right away.
Cheers,
Tru
