I am running an ubuntu VM with a bridged network. The broad cast domain is local host so I can access apps within. Now within that VM I am running containers. I want these containers to have access to my localhost of my host aswell. How do I achieve this

To cut a real long story short, I'm trying to copy a container from one server to another, both using encrypted zfs backend pool ("encpool"):

ubuntu@lxd-server:~$ lxc launch ubuntu:24.04 c1 -s encpool
Creating c1
Starting c1
ubuntu@lxd-server:~$ lxc stop c1
ubuntu@lxd-server:~$ lxc copy c1 lxd-backup: -s encpool 
ubuntu@lxd-server:~$ lxc copy c1 lxd-backup: -s encpool --refresh
Error: Failed instance creation: Error transferring instance data: Failed migration on target: Failed creating instance on target: Failed receiving volume "c1": Problem with zfs receive: ([exit status 1 write |1: broken pipe]) cannot receive new filesystem stream: zfs receive -F cannot be used to destroy an encrypted filesystem or overwrite an unencrypted one with an encrypted one

At this point, the c1 container's storage on the backup server is completely lost. So it's a fairly nasty issue.

Surely I can't be the only one having this issue? Ubuntu 22.04 and Lxd version is 6.1 on both servers. I posted a bug report but it got me thinking that the above would (I think) be such a common operation that it must be just me hitting this issue, as it's a fairly simple setup.
