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

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.
