Subject: [PATCH] selftest: kvm: kvm_page_table_test: change default guest memory down to 128MB
Date: Sun, 17 Dec 2023 18:41:08 +0900 [thread overview]
Message-ID: <20231217-selftest-dev-v1-1-52c338212fe8@linux.dev> (raw)
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.
