Following advice from a private message, I attempted to add the evdev option
within the QEMU XML (see https://libvirt.org/drvqemu.html for examples).
However this didn't work:

1) I ran 'virsh edit ...' and changed the opening line to:
<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>;
There were no objections from virsh but the change was simply discarded in the XML.

2) http://libvirt.org/schemas/domain/qemu/1.0 doesn't seem to be a
valid URL.

3) Adding <qemu:commandline> options to the XML threw a syntax error
from virsh.
