[PATCH 1/2] qemuxml2argvtest: disk-vhostuser: Add invocation for qemu-4.2

From: Peter Krempa <pkrempa(a)redhat.com&gt; With qemu versions prior to qemu-5.0 we'll format 'scsi=off' for virtio-blk disks, but also for vhost-user-blk. This is a bug as it's not supported. Add a test case to show that wrong configuration is generated by adding running 'disk-vhostuser' test case on capabilities from qemu-4.2. For this to be possible it's required to enable shared memory via NUMA configuration as old QEMU's don't allow configuration of the default memory backend. This is achieved by adding a copy of the 'disk-vhostuser' XML with NUMA enabled.
