layer3 cloud
an idea by bmwiedemann
Updated over 7 years ago. No love. Has no hacker: grab it!

One of the things that make deploying SUSE OpenStack Cloud hard is that it assumes that you have a layer2 network to do DHCP/PXE-boot, run your SDN on etc.

We should explore how easy it is to deploy a cloud across machines that can ping each other (OSI layer 3), but are in different networks - e.g a NUE desktop machine, a prague machine and a server in the NUE cloud network.

possible technologies that could help, include

  • gre, vxlan, multicast

  • ipsec, openvpn, tinc

If this needs too much patching in crowbar, we could explore ways with plain OpenStack, too.

has some success with

ip link add vxlan0 type vxlan id 42 group 239.1.1.42 dev eth0 dstport 4789
ip link set up dev vxlan0

but crowbar still tries to use eth0 - too much patching needed
