Disable KVM dnsmasq DHCP and TFTP
One or more guests are using the default host-guest KVM network and dnsmask provides DHCP, caching DNS (and TFTP) to the guests e.g.
# netstat -puta |grep dnsmasq
tcp 0 0 192.168.2.1:domain *:* LISTEN 709/dnsmasq
udp 0 0 192.168.2.1:domain *:* 709/dnsmasq
udp 0 0 *:bootps *:* 709/dnsmasq
Set other caching DNS and static IP address(es) in the guest(s)
View and backup the default KVM host-guest network configuration
# cd /etc/libvirt/qemu/networks
# stor default.xml
# cat default.xml
default

Stop the guest-host KVM network
# virsh net-destroy default
Edit the default KVM network
# virsh net-edit default
and get rid off the
... settings.
Start the network
# virsh net-start default
Network default started
