It looks like that was done as an ordinary user. Please could you repeat
as root

sudo lsof | grep dnsmasq.


I note that there's two instances of dnsmasq here, one started by
libvirt (?) and one, I guess, started by network-manager. I wonder if
some interaction between the two is what's causing the problem. Which
one is the which is spinning? Can you disable the libvirt stuff and see
if that makes a difference?


Cheers,


Simon.
