Cross posting from the charmhub forum, as I think this issue is better raised here.
Hello,
I am running Jammy on a dev box and am hitting some interesting issues launching centos7 lxd containers. Please keep in mind that launching the containers works as expected using 20.04.
I seemed to be blocked from using centos7 containers in general and with Juju.
$ juju add-machine --series centos7
$ juju status | grep centos7
15 pending juju-91c14c-15 centos7 Running
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.1 LTS
Release: 22.04
Codename: jammy
$ lxd --version

Error: The image used by this instance requires a CGroupV1 host system
Try `lxc info --show-log local:massive-dinosaur` for more info
If I build and import my own centos7 as opposed to using the upstream image, I am able launch the centos7 container, but it doesn’t get an ipaddress.
$ lxc launch juju/centos7/amd64 jca
Creating jca
Starting jca
$ lxc list | grep jca
| jca | RUNNING | | | CONTAINER | 0 |
We can see the ubuntu container does get an ipaddress though.
$ lxc launch ubuntu:22.04
Creating the instance
Instance name is: certain-mammoth
Starting certain-mammoth
$ lxc list | grep certain-mammoth

Introspecting a bit further, it seems the instance interface just doesn’t want to take an ip address, even when I try to force it by defining a static ip 
# cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
ONBOOT=yes
IPADDR=10.158.215.242
NETMASK=255.255.255.0
GATEWAY=10.158.215.1
[root@c1 ~]# ifconfig eth0

I suppose this is more of a lxd issue than a Juju issue, but Juju is definitely affected as centos7 deployments no longer work using the lxd/localhost provider.
Any ideas?
Possibly I need to file a bug with lxd somewhere.
Thank you
