Keir,
Thanks for your comments. Actually, I do not give a swap partition for both 
native and hvm guest when I do the test.
One point which deserves to mention is that the tests for hvm guest and xenu 
guest are based on the same image file, which helps to ensure that hvm and xenu 
guests share the same testing environment. At this point, xenu guest doesn't 
have a swap partition either, but cpu2k could run successfully with 1G memory 
in it.
Another point for reference is that cpu2k with 4 users could pass on ia32e hvm 
guest with 1G memory, which also does not have a swap partition.
Best regards,
Fan

When you tested with 1GB on native, did the native guest have a swap
partition? When testing on HVM, are you giving the HVM guest a swap
partition?
This does simply look like a straightforward out-of-memory condition.
Unsurprising if you're doing big userspace tests. What *is* interesting is
if it turns out that memory requirements running in an HVM guest are very
different from running on native. That shouldn't be the case.
