Installation ============ Diskimage-builder is run directly out of the source repository. Requirements ------------ If you have 4GB of available physical RAM (As reported by /proc/meminfo MemTotal), or more, diskimage-builder will create a tmpfs mount to build the image in. This will improve image build time by building in RAM. This can be disabled completely by passing --no-tmpfs to disk-image-create. ramdisk-image-create builds a regular image and then within that does ramdisk creation. If tmpfs is not used, you will need enough room in /tmp to store two uncompressed cloud images. If you do have tmpfs, you will still need /tmp space for one uncompressed cloud image and about 20% of that for working files. Installation ------------ * Clone the repository locally, then add bin to your path. * Make sure you have qemu-img (qemu-utils package on Ubuntu/Debian, qemu on Fedora/RHEL/openSUSE) and kpartx installed.
