network: add 'bootp' and 'tftp' config Currently, libvirtd will start a dnsmasq process for the virtual network, but (aside from killing the dnsmasq process and replacing it), there's no way to define tftp boot options. This change introduces the appropriate tags to the dhcp configuration: <network> <name>default</name> <bridge name="virbr%d" /> <forward/> <ip address="192.168.122.1" netmask="255.255.255.0"> <tftp root="/var/lib/tftproot" /> <dhcp> <range start="192.168.122.2" end="192.168.122.254" /> <bootp file="pxeboot.img"/> </dhcp> </ip> </network> When the attributes are present, these are passed to the arguments to dnsmasq: dnsmasq [...] --enable-tftp --tftp-root /srv/tftp --dhcp-boot pxeboot.img ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^ from <tftp /> from <bootp /> At present, only local tftp servers are supported (ie, dnsmasq runs as the tftp server), but we could improve this in future by adding a server= attribute.
