[one-users] CLVM - Clustered snapshots are not yet supported

[Marlok Tamás]

Hi!

If you have a working CLVM, then live migration should work with shared LVM
as well. Live migration is not working with pure LVM (only with workarounds)

FYI: If you are planning to update to 4.0, you should read the last comment
in here: http://dev.opennebula.org/issues/1341#note-4 (unfortunately auto
format crossed out half of my comment, but I hope it is still readable)

TL;DR:
We modified the original LVM driver, so it can work bot with LVM and CLVM

Cheers,
tmarlok
