Thread-topic: [Xen-ia64-devel] LTP system call case alarm04 Failed in xen0.
Hi Dan,

Sorry to reply you later. This case (alarm04) can pass in 
IA32/IA32e/IA64(Native Linux), IA32/IA32e/IA64(Xen/VTx, VTi) and IA32/IA32e 
(Xen/Xen0). It seemed only failed in IA64(Xen/Xen0) environment. :(

Best Regards,
Yongkang (Kangkang) 永康
