OpenNebula image for Scaleway
Update 2017-02-16: The problems with the recipes are now fixed and the image does all the configuration automatically. Scaleway is a provider bare metal servers that work pretty much as VMs. They boot from PXE and have the OS disk exported using nbd so spinning up new servers with different disk images is pretty fast. You can chose from x86 and arm processors, different number of cores and amount of RAM.
