The valgrind output was all fine - the warnings it issues are
all harmless.
The key is this message from the libvirt debug output:
> DEBUG: util.c: virExec (dnsmasq --keep-in-foreground --strict-order --bind-interfaces --pid-file --conf-file --listen-address 192.168.122.1 --except-interface lo --dhcp-leasefile=/var/lib/libvirt/dhcp-default.leases --dhcp-range 192.168.122.2,192.168.122.254)

This missing 'dnsmasq' binary is what is causing the 'defunct' process
you see. If you install dnsmasq it should all work as expected
