Hi,
I’m trying to set up LXD on Debian10. I can create containers, but they don’t get IPs
So far this is what I’ve done.
apt install snapd
snap install lxd
lxd init
Would you like to use LXD clustering? (yes/no) [default=no]: no
Do you want to configure a new storage pool? (yes/no) [default=yes]: yes
Name of the new storage pool [default=default]:
Name of the storage backend to use (btrfs, ceph, dir, lvm) [default=btrfs]: dir
Would you like to connect to a MAAS server? (yes/no) [default=no]:
Would you like to create a new local network bridge? (yes/no) [default=yes]: yes
What should the new bridge be called? [default=lxdbr0]:
What IPv4 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]:
What IPv6 address should be used? (CIDR subnet notation, “auto” or “none”) [default=auto]: none
Would you like LXD to be available over the network? (yes/no) [default=no]:
Would you like stale cached images to be updated automatically? (yes/no) [default=yes]
Would you like a YAML "lxd init" preseed to be printed? (yes/no) [default=no]:
Updated root’s path editing ~/.bashrc
with PATH=$PATH:/snap/bin
Created a container
lxc launch images:debian/buster mariadb
lxc stop mariadb
lxc network attach lxdbr0 mariadb eth0 eth0
lxc config device set mariadb eth0 ipv4.address 10.??.??.??
lxc start mariadb
lxc list
outputs
+---------+---------+------+------+------------+-----------+
| NAME | STATE | IPV4 | IPV6 | TYPE | SNAPSHOTS |
+---------+---------+------+------+------------+-----------+
| mariadb | RUNNING | | | PERSISTENT | 0 |

Here’s what ip add sh
ouputs

Could it possible be a firewall issue?

iptables-legacy
reports Input policy as ACCEPT and iptables
reports input policy as DROP (as I want it).
Any thoughts?
Thanks a lot.
