Chainloading Xen iPXE with dnsmasq

[James Dingwall]

Hi,

The version of iPXE embedded in the Xen HVM BIOS is not full featured so I would like to chainload a different version if the relevant feature indicators are not set in the DHCP request. I know how to do this with ISC DHCPD but I am stuck in an environment with dnsmasq. So far I can deal with the case where it is not iPXE with:

dhcp-match=IPXEBOOT,175
dhcp-option=175,8:1:1
dhcp-boot=net:#IPXEBOOT,undionly.kpxe
dhcp-boot=net:IPXEBOOT,http://<boot server>/boot.php

but I would like to dhcp-match to IPXEBOOT only when iscsi, menu, ... features are available.

Has anyone else managed to solve this?

Thanks,
James
