Subject: [PATCH] qemuxml2(argv|xml)test: Add case for validating proper DIMM
 slot validation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add a config where both DIMM and non-DIMM <memory> devices are used so
that it validates that only DIMMs require memory slots.
