Specify the memory size by using '-m size=2048k' instead of just '-m 2'.
The new syntax is used when memory hotplug is enabled. To preserve
memory sizing, if memory hotplug is disabled the size is rounded down to
the nearest mebibyte.

These are allegedly necessary to keep the output consistent,
but now that we're using a privileged config for the driver we
get the desired behavior out of the box, and as a bonus the
paths match what you would actually see on a regular host.

When trying to attach vhost-user-blk device to virtual machine using
qemu < 4.2 libvirt would mistakenly add a scsi=off parameter, which is
not supported by qemu.

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.
