I see; I observed the prompt and pause at boot time, and I assumed it represented an attempt to boot from the network. However, it looks like I just observed bug 625542, which I didn't see when searching since it doesn't appear on qemu-kvm's bug list, just ipxe. I've merged this bug with 625542, and marked 625542 as affecting qemu-kvm so it appears on the qemu-kvm bug list.
