Hi Li,

Although get on all VMs due low memory:

tst_test.c:1091: TCONF: No enough memory for tmpfs use

instead of
libswap.c:202: TCONF: Swapfile on tmpfs not implemented

I would also suggest to print who much memory is needed, e.g.:

diff --git lib/tst_test.c lib/tst_test.c
index edb42f7f4..151c6acca 100644
