The localdisk hook was a temporary solution and it is not recommended. I don't think anyone is testing this code and it is likely to be broken. We don't have a replacement with the same features, using logical volumes on a local disk (e.g. fast ssd), but if you want to attach the entire device to vm, it should be possible to do this without any hacks in 4.4. The main issue with the localdisk hooks is that engine does not understand what the hook is doing, and the changes made by the hooks behind engine back can cause lot of breakage. Any storage operation on the disks used for the local disk may fail or cause trouble.
