Hello everybody.
I'm actualy experiencing some problem for ordering my VM boot with
qemu-kvm / Seabios and gPXE.
I use libvirt's per-device boot option which launch my VM with this
options :
You can find libvirt's xml there : http://pastebin.com/bqizkLiZ

We see the right bootindex option as I want to boot on gPXE from my
second NIC (mac=52:54:00:28:ca:e6).
The problem is that during my VM boot process, seabios initialise gPXE
for my 2 NIC.
But then gPXE try to boot (DHCP request) on the first NIC rather than on
the second one.
It always try to boot first on the first PCI device (00:03.0 instead of
00:04.0).
I don't really know if the problem comes from gPXE or Seabios but I have
exactly the same problem when I try with Ubuntu's etherboot rom.
I got this problem with Ubuntu latest qemu-kvm
(0.14.1+noroms-0ubuntu3.11.04.1) / seabios (0.6.2-0ubuntu1) and
etherboot (5.4.4-7ubuntu2) and Fedora qemu-kvm
(qemu-kvm-0.15.0-4.fc15.x86_64) / Seabios
(seabios-bin-0.6.2-2.fc15.noarch) and gPXE
(gpxe-roms-qemu-1.0.1-4.fc15.noarch).
I also recompiled latest Seabios (pre-0.6.3-20110929) trunk and gPXE
(1.0.1+) from Git : the behaviour is exactly the same. I tried with
different NIC driver (virtio and rtl8139) with also same behavior.
Do you have any idea where my problem can come from ?
Thanks in advance for any advice.
Regards,
Romain Vrignaud
