Hello,
I want to use PXE boot in kvm's virtual machines, but I've not found, how to
configure libvirt for starting dhcp server with correct options for this.
Now i have libvirt-0.5.1-2.fc10.x86_64 and virt-manager-0.6.0-5.fc10.x86_64,
I've created VM using virt manager, with specifying PXE boot option. VM config
contains following sections:
<os>
<type arch='x86_64' machine='pc'>hvm</type>
<boot dev='network'/>
</os>
.....
<interface type='network'>
<mac address='54:52:00:0a:f6:00'/>
<source network='nat_net'/>
<model type='virtio'/>
</interface>
and config for virtual network nat_net:
<network>
<name>nat_net</name>
<uuid>e02cfc6f-d7f8-6f81-8c19-bfa9d2a13a85</uuid>
<forward dev='eth0' mode='nat'/>
<bridge stp='on' forwardDelay='0' />
<ip address='192.168.107.1' netmask='255.255.255.0'>
<dhcp>
<range start='192.168.107.128' end='192.168.107.254' />
</dhcp>
</ip>
</network>
dnsmasq starts with following command line:
/usr/sbin/dnsmasq --keep-in-foreground --strict-order --bind-interfaces--pid-
file --conf-file --listen-address 192.168.107.1 --except-interface lo --dhcp-
leasefile=/var/lib/libvirt/dhcp-nat_net.leases --dhcp-range
192.168.107.128,192.168.107.254
But for working PXE boot it should have also something like
--dhcp-boot=pxelinux.0,itchy,192.168.107.1
So after starting VM it tries to boot from network, gets DHCP response and
reports, that it doesn't contains filename option.
So the question is - how to get it working correctly ? (If i start dnsmasq by
hand with option --dhcp-boot=pxelinux.0,itchy,192.168.107.1 PXE boot works)
