The obvious stupid question to ask it this: Are you sure you mount every iSCSI 
device only once? That would be the most obvious explanation for file system 
corruption while the OS is running.

AFAIR, the e2fsck package when being built can run an extensive set of 
self-tests. 
Maybe if you perform such a build on a iSCSI device, you could see how it goes. 
If 
it's without problems, the obvious thing to test would be the same situation 
without XEN (if possible). If there's corruption even without XEN, something is 
severely wrong.
