Hi all, how I can set dhcp options as DNS, gateway, etc in libvirt's network definitions?
The default GW depends on the IP address you assigned to your network: <ip address='192.168.122.1' netmask='255.255.255.0'/> This says the default GW is 192.168.122.1/24. However, you can insert other routes too: <route address="192.168.222.0" prefix="24" gateway="192.168.122.2"/> For handling DNS, you need to focus on <dns/> element. For instance, to set a different forwarder than GW: <dns> <forwarder addr="8.8.8.8"/> </dns> It's all documented here: https://libvirt.org/formatnetwork.html#elementsStaticroute and in the subsequent section.
From what I read here[1], I can use the <option> tag. However, I can not find nothing on libvirt official documentation.
No, that was just a proposal. RFC, a discussion how should we implement some special features of DHCP. Those are not patches and in fact patches implementing that were never merged. Michal
