to get migrations, the storage for a VM must be equally accessible from both 
hosts; if you use file-backed storage, that means accessing a shared 
filesystem, typically NFS.  if you use block-level storage, that means 
accessing a shared block-storage, that's a SAN.

the shared block-storage must be partitioned somehow, the most 'linux' way to 
do it is LVM (the other way is to use LUNs on the block devices, don't know 
much about this).  it's more manageable to use CLVM, or EVMS-heartbeat, but 
that's all, you don't need the full GFS stack.
