Thus hardly depend from your application in detail, but it should very less 
depend from xen what kind of data you will lost with a OS crash like yours.

Crashing a DomU is mainly like crashing a real OS.

Depending from your apps it may be that filesys buffers over longer time are 
not written / synced to disc.

You may try to seek in your swap against some helpful data (even this depends 
from your app) and if you have no snapshots or backups in between there is 
nothing other to save anymore.


best regards,

Niels.
