Seems like 'no permission' error at lower levels. Check xapi user/group 
and if xenops has rights to access raw partitions (xapi communicate with 
xenops, xenops calls pygrub, pygrub extract kernel and modules, xenops 
call xl toolstack to create VM.
If that process is broken due lack of permissions, VM will not start.
