What am i doing wrong?
from recollection, i could only get iPXE + libvirt + KVM/qemu to work if i used the e1000 driver in libvirt, even with the rom type that should match for virtIO net. to debug, leave off the EMBED so you can get an interactive iPXE shell, and then run "ifstat". if you aren't getting any net# devices, the drivers aren't loaded/working with the provided virtual hardware. you can also build with debug flags to get more information: http://ipxe.org/download#debug_builds i *think* the proper DEBUG= for this case would be "DEBUG=netdevice" but i'd need confirmation on that. was this working in the past? if so, it's a bit time-consuming but if you know the commit/tag/release in which it was working, you could do a git bisect (primer[0], man page[1], documentation[2]) - that'll narrow down the exact commit in which things went wonky.
