I haven't looked at the XCP code yet, but are there some special patches for
LVM to make it work in a shared environment on multiple hosts? 

I guess it's not CLVM, since you support snapshots.. so xapi is doing
some coordination of management commands and making sure only one LVM
command is issued at a time?

And after making changes to the LVM configuration xapi runs 'vgscan' on
every host to pick up the changes? 

Thanks!
