[libvirt] [RFC PATCH auto partition NUMA guest domains v1 2/2] qemuxml2argv: add tests that exercise vNUMA auto partition topology

[Wim Ten Have]

From: Wim ten Have <wim.ten.have at oracle.com>

Add tests to ensure that the virDomainNumaAutoconfig() routine to auto-
partition vNUMA topology generates correct KVM/QEMU cmdline arguments
under applicable <cpu mode="host-passthrough" check="numa"> setup.
