My VMs don't get IP with libvirt and dnsmasq

[Computers Issues]

Hi,

That was right. I mean, I've tried it at the same time in both machines I
have (the one where it works and the other), and using tcpdump -i virbr2 in
both ones, after creating the domain with virsh, showed that the right one
is getting DHCP traffic, but there's no DHCP request or anything about DHCP
in the one that is not working.
