[Qemu-devel] Netboot happens twice (first fail) when using etherboot ROMs

[Michael Tokarev]

I wonder why with etherboot ROMs, the network boot
happens two times (0.12.x), like this:

The boot ROMs supplied with the source works as expected.

What's the difference?  Is gpxe behaves differently, or
is that a difference in build options?

(This applies to both qemu and qemu-kvm).

Thanks!
