Question about microovn

Hi all,

I was recently trying to use microovn
I run sudo microovn init just like in case of microceph

mother@infra1:~$ sudo microovn status
MicroOVN deployment summary:
- infra1 (10.10.11.11)
  Services: central, chassis, switch
- infra2 (10.10.11.12)
  Services: central, chassis, switch
- infra3 (10.10.11.13)
  Services: central, chassis, switch
mother@infra1:~$ lxc network delete UPLINK
Network UPLINK deleted
mother@infra1:~$ sudo microovn init
MicroOVN has already been initialized.

Would you like to add additional servers to the cluster? (yes/no) [default=no]:
mother@infra1:~$ sudo microovn status
MicroOVN deployment summary:
- infra1 (10.10.11.11)
  Services: central, chassis, switch
- infra2 (10.10.11.12)
  Services: central, chassis, switch
- infra3 (10.10.11.13)
  Services: central, chassis, switch

but I am wondering if there should not be any new network created

lxc network ls

Can I debug it somehow?

Thx

MicroOVN by itself won’t create any new networks because it wouldn’t know what sort of network configuration to create. Its a framework for creating overlay networks, but they are very customisable and so it doesn’t create anything by default.

My understanding is that MicroCloud will use LXD with MicroOVN to configure a default LXD OVN network (which is an OVN network configured in LXD’s way).
