Created attachment 791951 [details] iPXE script in which the DHCP request fails Description of problem: When I start a very basic KVM instance under libvirt (one NIC, set to PXE boot) iPXE successfully completes DHCP and then fetches my iPXE script (attached) from my tftp server. That script asks the VM to DHCP again on that interface; that second round of DHCP does not complete successfully - I can see the DHCPDISCOVER and DHCPOFFER in my log files, but the VM never sends a DHCPREQUEST (and there's then no subsequent DHCPACK) If I replace the 1af41000.rom with the one from Fedora 18, this all works.
I built an RPM with latest ipxe git, can you give that a spin and see if makes any difference? http://koji.fedoraproject.org/koji/taskinfo?taskID=5877738
Unfortunately, this does not fix the issue for me - still the exact same symtpoms. If it makes any difference, I am running this on a local libvirt network; network XML is attached. I use a VM with one NIC, connected to that network.

With ipxe-20140303-1.gitff1e7fc7.fc20, this seems to be fixed. Please reopen if that's not the case.
