Yeah, it does seem to be the case. I ran a few experiments after reading your message: kvm-28 and kvm-36 successfully PXE-boots when using bios.bin from kvm-28, but both fails to PXE-boot when using bios.bin from kvm-36. > Can you try a more recent KVM with -no-kvm? Using the patch I posted to the list, I can PXE-boot using the qemu-system-x86_64 executable from kvm-36 both with and without kvm kernel module acceleration (provided that I use the bios from kvm-28, that is).

It worked for me (qemu-system-x86_64 from kvm28, atftpd serving i386 dapper ubuntu-installer image over tap networking device). Could you clarify what "PXE boot hasn't ever worked with qemu-system-x86_64" means? -- Chuan-kai Lin - This SF.net email is sponsored by: Splunk Inc.

As long as PXE booting works both with and without kvm, I don't care which one gets included either. -- Chuan-kai Lin - This SF.net email is sponsored by: Splunk Inc.

[kvm-devel] [PATCH] Fix network boot whether KVM is enabled or disabled
From: Chuan-kai Lin <[EMAIL PROTECTED]>
This patch is based on the one Anthony Liguori submitted to kvm-devel
on July 2nd, which fixes PXE booting with KVM enabled but breaks PXE
booting when not using KVM. I simplified Anthony's patch and
duplicated the cpu_register_physical_memory call to ensure that the
code retains its original behavior when kvm_allowed is 0.
