Thanks for hint. Indeed it's a matter of prefix.
So the archive tarball has to be created in a way:

~/meta# tar cJf ../meta.tar.xz *

~/meta# tar tf ../meta.tar.xz
metadata.yaml
templates/
templates/upstart-override.tpl
templates/hostname.tpl
templates/hosts.tpl


Creating it differently (which practically gives same result in terms
of decompression) makes LXD to generate error:

~/meta# tar cJf ../meta.tar.xz .
or
~# tar cJf meta.tar.xz -C meta .

~/meta# tar tf ../meta.tar.xz
./
./metadata.yaml
./templates/
./templates/upstart-override.tpl
./templates/hostname.tpl
./templates/hosts.tpl
