Solution to LXD IP address already defined on another NIC error

If you have previously assigned a fixed IP address when replicating a container, you are likely to encounter this error.

To solve the error:

When you copy, you will need to duplicate it by adding the interface name and IPv4 address to the end.

For example: -d eth0,ipv4.address=10.35.38.31

lxc copy hope -d eth0,ipv4.address=ipaddress
