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. --- Signed-off-by: Itaru Kitayama <itaru.kitayama@linux.dev> --- tools/testing/selftests/kvm/kvm_page_table_test.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) --- base-commit: a39b6ac3781d46ba18193c9dbb2110f31e9bffe9 change-id: 20231217-selftest-dev-c769544c303d Best regards,
