No, in your instance config you have shown two NIC devices both connected to the same lxdbr0:
devices:
eno1:
nictype: bridged
parent: lxdbr0
type: nic
eth0:
name: eth0
network: lxdbr0
type: nic
The devices are named eno1 and eth0.
The instance name will be setup in dnsmasq’s DNS pointing to the NIC’s DHCP IP address.
However if you connect multiple NICs to the the same parent bridge (lxdbr0 in this case) then there is the possibility that both NICs will have DHCP run on them and this would result in multiple IPs for the same DNS name, causing unpredictability.
If you don’t know of the reason why you have two NICs on your container, then I suggest removing one (probably the eno1 one, as the eth0 is more conventional) and see if that solves the issue.
