+Subject: test: qemuxml2argv: Mock virMemoryMaxValue to remove 32/64 bit
+ difference
+
+Always return LLONG_MAX even on 32 bit systems. The limitation
+originates from our use of "unsigned long" in several APIs. The internal
+data type is unsigned long long. Make the test suite deterministic by
+removing the architecture difference.
+
+Flaw was introduced in 645881139b3d2c86acf9d644c3a1471520bc9e57 where
+I've added a test that uses too large numbers.
