Hello All,
I am trying to set up a cobbler server running as a guest on an isolated
network. I'm having trouble figuring out how I can forward the DHCP and DNS
traffic to this guest instead of DNSMASQ on the host. So far I have only
tried to get dhcp working by enabling the 'allow-dhcp-server' on a guest
named test and setting the $DHCPSERVER variable through a filterref
parameter element. I figure If I can get this working I can use this filter
as a basis for DNS.
In my guest the filter is applied to the only network interface setting
DHCPSERVER to the IP of my cobbler VM.
<interface type='network'>
<mac address='52:54:00:6b:56:ab'/>
<source network='internal'/>
<target dev='vnet2'/>
<model type='virtio'/>
<filterref filter='allow-dhcp-server'>
<parameter name='DHCPSERVER'
value='192.168.100.2'/>
</filterref>
<address type='pci' domain='0x0000' bus='0x00'
slot='0x03'
function='0x0'/>
</interface>
And the internal network is defined as:
<network>
<name>internal</name>
<uuid>c1aef8ea-9d30-7514-5eb4-5ffbc235cffb</uuid>
<bridge name='virbr1' stp='on' delay='0' />
<ip address='192.168.100.1' netmask='255.255.255.0'>
</ip>
</network>
My understanding of the filter is that when it is applied to a hosts
interface it should allow DHCP requests to go to a server other than the
host system. Is this correct? Are guests allowed to serve DHCP to other
guests?
Does anyone have any suggestions or experience with this?
Thanks in advance,
Adam Reid
