Hello everyone,
I have multiple virtual networks defined on my Server:
# virsh net-list --all
Name State Autostart Persistent
----------------------------------------------------------
default active yes yes
...
virtual-mgt-5 active yes yes
...
When a VM is started on one of them with an interface which needs the dnsmasq DHCP server to get its IP address/len, it remains inaccessible with the FQDN once the IP information is acquired.
The default values are used for each dnsmasq instance:
● libvirtd.service - Virtualization daemon

I wonder whether the option "--leasefile-ro" gets in the way or not: there must be a key=value in /etc/libvirt/qemu/networks/<virtual_network>.xml to enable this behavior, but could not find it in the Network XML format.
The contents of my XML file are:
<network ipv6='yes'>
<name>virtual-mgt-5</name>
<uuid>193ac2c9-13fc-44a6-83f8-477790f1f470</uuid>
<forward mode='route'/>
<bridge name='virbr5' stp='on' delay='0'/>
<mac address='52:54:00:b9:ea:63'/>
<domain name='actionmystique.net'/>
<ip address='172.21.0.1' netmask='255.255.0.0'>
<dhcp>
<range start='172.21.0.1' end='172.21.255.254'/>
</dhcp>
</ip>
<ip family='ipv6' address='fc21::1' prefix='64'>
<dhcp>
<range start='fc21::1' end='fc21::fffe'/>
</dhcp>
</ip>
</network>
Any suggestion?
