Ive been trying to follow Canonicals implantation of Micro Cloud - which is know is just packaging up LXC/OVN/Ceph, and Im running into issues with the default network link. Im not following their instructions to the T since Im creating 3 Ubuntu 22.04 VMs, and then building them out from there. Each of the VMs have dual nics assigned to them.
Main nic: eth0 - dhcp from pfsense router
Second nic: ens19 - no ip - using for the distributed networking
Output from the servers is identical for Netplan:
network:
version: 2
ethernets:
eth0:
dhcp4: true
dhcp6: no
match:
macaddress: 3a:29:b2:d8:8d:25
set-name: eth0
ens19:
dhcp4: no
dhcp6: no
link-local: []
I had to set the link-local since it was showing an IPv6 address, and LXC will ignore it if there is an address.
Output for the interfaces:

What in the world am I missing? I can’t ping that volatile IPv4 address.
