[libvirt-users] Questión about DNS config on dnsmasq

Hello guys... I'm using libvirt in my local laboratory and I have a question/problem about DNS settings over dnsmasq (by libvirt) I have a NAT network separately from my real network, i need simulated some DNS hosts to NAT network like ftp.debian.org (for testing purposes, etc) This is for example a dumpxml (yes, i'm using PXE boot for testing and is working fine) <network> <name>net0</name> <uuid>5a014735-f658-7a87-c7d4-e6b0f488c332</uuid> <forward mode='nat'/> <bridge name='net0' stp='on' delay='0'/> <mac address='52:54:00:b5:24:7b'/> <dns> <host ip='192.168.122.1'> <hostname>mirrors.kernel.org</hostname> <hostname>mirrors.dcarsat.com.ar</hostname> <hostname>ftp.debian.org</hostname> </host> </dns> <ip address='192.168.122.1' netmask='255.255.255.0'> <tftp root='/home/tftp'/> <dhcp> <range start='192.168.122.2' end='192.168.122.99'/> <bootp file='pxelinux.0'/> </dhcp> </ip> </network> Look <dns> & <hostname> section, that works correctly but only if I add hostnames on net0 when was offline. <dns> <host ip='192.168.122.1'> <hostname>mirrors.kernel.org</hostname> <hostname>mirrors.dcarsat.com.ar</hostname> <hostname>ftp.debian.org</hostname> </host> </dns> How i can add more hostnames with my network (net0) are still online...? virsh net-update default add-last dns-host (for example, doesn't work) and the official documentation @ http://libvirt.org/formatnetwork.html#elementsAddress doesn't say more. I test with <forwarder > but doesn't work (192.168.10.100 is a dnsmasq outside libvirt control) <network> <name>net0</name> <uuid>5a014735-f658-7a87-c7d4-e6b0f488c332</uuid> <forward mode='nat'/> <bridge name='net0' stp='on' delay='0'/> <mac address='52:54:00:b5:24:7b'/> <dns> <forwarder addr="192.168.10.100"/> </dns> <ip address='192.168.122.1' netmask='255.255.255.0'> <tftp root='/home/tftp'/> <dhcp> <range start='192.168.122.2' end='192.168.122.99'/> <bootp file='pxelinux.0'/> </dhcp> </ip> </network> Anyone can help me...? thanks -- "La Voluntad es el único motor de nuestros logros" http://blog.ngen.com.ar/
