kvm_page_table_test's current default guest memory is set to 1GB, however on a 4GB of system memory this setting causes an OOM event. While it is able to control the test program arguments using an environment variable, KSELFTEST_KVM_PAGE_TABLE_TEST_ARGS, it is not intuitively clear for a selftest users the above variable exists, change the default guest memory down to 128MB so that small systems can run this test without seeing an OOM.
