Sorry I did not have a VM by that time. Now I do :) Apparently it needs more memory, as first thing DPDK does is reserving space in rte_malloc heap, which size is bigger in the VM. By changing the memory needed to 18M, we can fix the unit test. I am still not sure why within a VM we need more memory, though. Thanks, Pablo > > -- > Thomas
