How about Linux guests that have file systems stored on FCP attached

I suspect that you would still need some kind of cluster file system
(eg, Lustre, GFS, OCFS, etc) to make that safe.
To amplify David's response: I think it works like other kinds of
DASD: if *everyone* has it read-only, that's OK. If *anyone* has it
read-write at the same time that anyone else has either a read-only or
read-write link to it, then you need some sort of cluster-aware
filesystem to share it correctly.
