dnsmasq(as DHCP server) isn't working in KVM+libvirt envirmont
- by user2681054
I'm using dnsmasq as DHCP server in VM environment.
But It didn't working. I disabled basic DHCP feature in libvirt.
<network>
<name>default</name>
<uuid>84da0678-e56d-8fc2-6f8b-e8eba784849a</uuid>
<forward mode='nat'/>
<bridge name='virbr0' stp='on' delay='0' />
<mac address='52:54:00:7B:64:0B'/>
<ip address='192.168.122.1' netmask='255.255.255.0'>
</ip>
</network>
As you can see, I removed this tag!
<dhcp>
<range start='192.168.122.2' end='192.168.122.254' />
</dhcp>
And I installed dnsmasq in Host machine. During installation dnsmasq, there was an error message about 127.0.0.1.(dnsmasq: failed to create listening socket for 127.0.0.1) So I commented out listen-address option, and added dhcp-range/dhcp-option options, like this.
listen-address=127.0.0.1
dhcp-range=192.168.122.100,192.168.122.200,24h
dhcp-option=option:router,192.168.122.1
That's all I've done with dnsmasq. But guest VM couldn't get IP address from host which is dnsmasq server running.
After that , I installed isc-dhcp-server instead of dnsmasq.... and it works! But I still want to use dnsmasq instead of isc-dhcp-server. Are there any helping hands?
I disabled host machine's firewall.
I've heard that libvirt basically use dnsmasq. Is this the reason why I couldn't use dnsmasq in libvirt environment?
