Hello,
I’m trying to set a default gateway on an isolated lan (because one of my VM get access to an other lan).
I’m trying to use the option <route > but this doesn’t affect the default route on my VMs.
Here is the network xml
<network>
<name>prd-private-lan</name>
<uuid>2222222222222222222222</uuid>
<bridge name='virbr3' stp='off' delay='0'/>
<mac address='52:54:00:08:1e:d8'/>
<domain name=‘pre' />
<dns>
<forwarder addr='8.8.4.4'/>
<forwarder addr='8.8.8.8'/>
</dns>
<ip address='10.10.0.1' netmask='255.255.255.0'>
<dhcp>
<range start='10.10.0.128' end='10.10.0.254’/>
<host mac=‘xxxxxx' name=‘finternet.pret' ip='10.10.0.7'/>
</dhcp>
</ip>
<route address='10.10.0.0' netmask='255.255.255.0' gateway='10.10.0.7'/>
</network>
And here is what I get on the guest VM connected to the pre-private-lan
route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.10.0.0 0.0.0.0 255.255.255.0 U 100 0 0 ens4
Can someone help me or tell me what to do ?
What I’m a bit surprise is the file //var/lib/libvirt/dnsmasq/prd-private-lan.conf doesn’t contain any clause defining the new gateway. Something like ‘dhcp-option=3,10.10.0.7'
strict-order
no-resolv
server=8.8.4.4
server=8.8.8.8
domain=prd.pipiche.net
expand-hosts
pid-file=/var/run/libvirt/network/prd-private-lan.pid
except-interface=lo
bind-dynamic
interface=virbr3
dhcp-option=3
no-resolv
dhcp-range=10.10.0.128,10.10.0.254
dhcp-no-override
dhcp-lease-max=127
dhcp-hostsfile=/var/lib/libvirt/dnsmasq/prd-private-lan.hostsfile
addn-hosts=/var/lib/libvirt/dnsmasq/prd-private-lan.addnhosts
Of course I can add an explicit route on the guest - so did I - but for maintenance purposes I would like to avoid and have all configuration in the network XML
Thanks in advance
Patrick
