similar to: kernel is not a bzImage

This implements a loader for version 2.07 boot protocol bzImage format files. This allows a single bzImage kernel file to boot either native from a normal bootloader (grub, etc), or paravirtualized under Xen. These bzImages have two changes to make this possible: 1. There's a new field for the bootloader to tell the booted kernel what kind of environment its coming up under. We

Hi, Today I replaced grub(1) with syslinux on my laptop, after rebooting to syslinux and selecting kernel I got massive freeze along with colorful output to screen - http://i.imgur.com/lFjFc.jpg I think I tried everything, even doing esc and writing after boot: /bzImage-3.1.0, after enter I had the same freeze with the same screen artefacts. How I installed extlinux: mkdir /boot/extlinux

Hi, What the the size limit of booting bzImage file with syslinux ? I have tested different sized bzImage files, and when the files are small <800K, they work with syslinuz, but at some size larger they fail to work. This was the same problem loadlin1.6 had, but loadlin1.6c fixes the issue, and I can boot bzImage sizes up to 1.5Meg with loadlin, but syslinux fails. Can you confirm this

Package: src:xen Version: 4.1.3-4 Severity: serious The bzimage loader used in both libxc and the hypervisor lacks XZ support. Debian kernels since 3.6 are compressed with XZ and can't be loaded. Support for XZ compression was added in changeset 23002:eb64b8f8eebb somewhere last year. Bastian -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (990,

Well, it seems to be about time to have this conversation again. A rough overview of the previous thread and requirements is: 1. bzImage would not be a bare ELF file, but it would contain an ELF header+file within it 2. We need some way to add extra ELF notes into that ELF file 3. We use a "paravirtualized" bootloader type, with some other field to determine which

I am running XEN on CentOS Linux release 7.8.2003 I have a Debian 7, and two Gentoo DomU Guests running fine. I am trying to get an Ubuntu 20.04 DomU Guest running but I get this error when trying to run the netboot kernel image xc_dom_probe_bzimage_kernel unable to LZ4 decompress kernel I understand that CentOS Xen does not support LZ4 decompression. Is there a workaround for this?

Package: xen-utils-3.2-1 Version: 3.2.1-2 Severity: important Hi, I set the severity to important as it seems that current xen tools does not allow to load amd64 Debian kernel in DomU. I also put the debian-kernel ML in CC as I'm not sure the problem comes from xen tools or the kernel itself. Here is my configuration: Hypervisor: xen-hypervisor-3.2-1-amd64 3.2.1-2

Package: xen-hypervisor-3.2-1-amd64 Version: 3.2.1-2 Severity: serious After noting that this version supposedly loads bzImage kernels: | xen-3 (3.2.1-2) unstable; urgency=low | | * Use e2fslibs based ext2 support for pygrub. (closes: #476366) | * Fix missing checks in pvfb code. | See CVE-2008-1952. (closes: #487095) | * Add support for loading bzImage files. (closes: #474509) | *

Thanks all, It should be quick, so it will be implemented in C. Maybe I should have stated that I am not an expert in syslinux (intelligent but no expert). I think that I understand the "custom COM32 module" option : I simply have to change the code (and begin by looking into the files that were suggested). As for Peter's suggestion, I am not sure if I understood. Is this an

I started with Vivek's ELF bzImage patch from Oct last year, mashed it to apply to hpa's new setup/boot code. This patch does a couple of things, which would probably be better split into multiple patches: 1. Glue an ELF header onto the front of bzImage. This is a real ELF header at the front of the file. Breaks akpm's laptop, apparently, but it works for me. 2.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I am trying to setup a DomU with linux-2.6.18-xen.hg in order to test Remus on a Debian Squeeze 6.0 / Xen 4.0.1 (2.6.32-5-xen-amd64) Dom0. After applying several patches to the Debian Squeeze Xen packages, I have built the linux-2.6.18-xen.hg, but when I start my DomU, I have got this error message : Error: (2, ''Invalid

I want to run the examples of a book titled "The Definitive Guide to the Xen Hypervisor", but Xen4.x seems not support the examples and says something like xc: error: panic: xc_dom_bzimageloader.c:607: xc_dom_probe_bzimage_kernel: kernel is not a bzImage: Invalid kernel So I have to install Xen3.4. On vmware, I follow the instructions from Internet to install Ubuntu 1004 with kernel

OK, here's another go-around. This patch leaves the bzImage itself unmodified, but it changes the payload into an ELF file. That is, the 32-bit decompression/relocation+compressed kernel is now a properly formed ELF file. One thing that fell out of this is that code32_start end up being a pointer to the ELF header rather than an entrypoint. Rather than reproducing Vivek's (?) hack of
