How about Linux guests that have file systems stored on FCP attached
SCSI devices, can they be shared r/o with other Linux guests? My
understanding is that, no, they can not be shared. Am I mistaken?

Anyone remember AFS?
I never fully understood why, but AFS seemed to have a fondness for
"write access here / read access there".  You really need
something like that for effective filesystem sharing.
Control the writing, then share the reading widely.

AFS is now open source, so it's a very nice option. And it works fine on Z. 8-)

Contuing to treat virtual Linux the same as discrete Linux
really throws away much of the value of virtualization.

Indeed. I find that thinking about embedded systems often works better than 
comparing to discrete systems.
