That is not true. Any query sent to @192.168.122.1 would get reply. I
use for example unbound on localhost and all my machines use .vm. domain
suffix. rhel7.vm. is machine with rhel7. Dnsmasq manages automatically
lease names of all its dhcp clients, it works as dynamic DNS connected
with DHCP just out of the box.
I've created a libvirt hook to do the integration I was looking for. This works for me:
/etc/libvirt/hooks/network.d/laptop-lab.sh
#!/bin/bash
set -o nounset
object="$1"
operation="$2"
suboperation="$3"
extra="$4"
if [ "$object" == "laptop-lab" ]; then
if [ "$operation" == "started" ] && [ "$suboperation" == "begin" ]; then
/usr/bin/resolvectl dns laptop-lab 192.168.100.1
/usr/bin/resolvectl domain laptop-lab laptop.lab
/usr/bin/resolvectl dnssec laptop-lab no
fi
fi
set -o nounset
object="$1"
operation="$2"
suboperation="$3"
extra="$4"
if [ "$object" == "laptop-lab" ]; then
if [ "$operation" == "started" ] && [ "$suboperation" == "begin" ]; then
/usr/bin/resolvectl dns laptop-lab 192.168.100.1
/usr/bin/resolvectl domain laptop-lab laptop.lab
/usr/bin/resolvectl dnssec laptop-lab no
fi
fi
