In our kickstart menu, we need to do a hostname lookup to choose the appropriate local server as there are different boot servers in different global locations. For this, we are currently relying upon the 'nslookup' command, which is available in Xen and VMWare pxe command sets, but the oVirt/KVM one does not have this command enabled. I've tried a workaround using php commands, e.g.:

we’re updating to a new ipxe[1] soon, so you can give it a try if it maybe works (i dont’ see the option added though) or if there is some other way how to do that
otherwise I guess you would have to recompile, but if you bump up the version yourself and put it into your own repo it should always have a precedence

Thanks,
