Hey Alexandre, I don't know if you're already tinkering with rsyncing the iso images, and wanted to let you know that I'm currently experimenting with qemu's vvfat drive option. According to the source it should work across migrations as long as it's used read-only. I tested migrating in a virtual testcluster and it seemed to work. It basically takes a directory, loads the list of contained files and presents the guest OS with a fat16 formatted partition on a block device. The downside of it is that we need the qemu patch I posted earlier to label the partition, as cloud-init needs it to be labeled "config-2", but qemu's vvfat default is hardcoded to "QEMU VVFAT". The change is small enough though, so maybe they even accept it upstream...
