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 a 'netboot' tag to the dhcp configuration:
<network> <name>default</name> <bridge name="virbr%d" /> <forward/> <ip address="192.168.122.1" netmask="255.255.255.0"> <dhcp> <range start="192.168.122.2" end="192.168.122.254" /> <netboot root="/srv/tftp" file="pxeboot.img"/> </dhcp> </ip> </network>
When root= and file= attributes are present, these are passed to the arguments to dnsmasq:
dnsmasq [...] --enable-tftp --tftp-root /srv/tftp --dhcp-boot pxeboot.img
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.
I very much like this idea - e.g. I'd really like to have this to give people simple instructions for testing gPXE in next week's Fedora Test Day.
The argument was made before that it's pointless to use PXE like this when you can just explicitly configure a kernel/initrd, but that misses the point that sometimes you do explicitly want to use PXE, even just for testing purposes.
Patch looks good to me too, ACK
I like the idea too. But this opens the door to outside access or just limits it to the guest ? In any case make sure you have an up to date dnsmasq https://cert.belnet.be/belnetadvisories/rhsa-20091238-01-important-dnsmasq-s...
