@wirwolf if you don't mind, let's take this to https://github.com/neoaggelos/cluster-api-provider-lxc ! super excited to have a v0.1.0 out. would appreciate if you could create bug reports for them. but in general:

  • re instances in incus0 and incus1 not communicating, is 10.117.223.1/24 a local bridge on both nodes? if so, then it's a separate local bridge and cross node traffic would not work. you either need ovn for cross-node traffic, or configuring bridges/macvlan. working on adding some documentation on this subject and point to upstream incus docs for more.

  • interesting that there is no hostname on the eth0 interface. What type of network are you using?

If you can create a github issue for each in https://github.com/neoaggelos/cluster-api-provider-lxc/issues, it would be ideal
