We don't follow any how-to for that, but things are quiet simple.
We decided that a VG is dedicated for each domU, and one LV on this VG for each disk of the domU (generally only one). We use naming rules to avoid to get lost with this big amount of LVs.

When you want to migrate a domU, you must attach the SAN disk on which resides the domU's VG to the target dom0, and you must activate its LVs.
The "xm migrate -l" may be runned, generally it succeeds... except in some cases like the one I reported here.

Don't hesitate to ask me if you have further questions.

Auf viedersen.
Alain.
