The destination lxd will try to connect to the source lxd directly to
perform the copy.

You can probably try something like this:
lxc copy local:src_vm remote_name:dst_vm

where "local" is the literal string local. If that doesn't work, try adding
the local IP as another remote (e.g. "lxc remote add local_instance
127.0.0.1") and then retry the copy with "lxc copy local_instance:src_vm
remote_name:dst_vm".

The idea is to treat both src and dst lxd as remotes, so that traffic will
go thru lxc process instead of directly between lxd daemons. Last time I
tested it works.
