search for: xc_dom_probe_bzimage_kernel

Hello list, Since a few months I get the following error after I have recompiled Xen from hg, xen-4.1-stable or xen-unstable: ERROR Invalid kernel: xc_dom_probe_bzimage_kernel: kernel is not a bzImage This comes from domU''s that are configured to use pv-grub. As a workaround I do have a working pvgrub-x86_64.gz from an earlier compile so I''m using that without problems. But new compiles always fail for me. How come? Thanks, -Mark

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? Regards Francis -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos-virt/attachments/2020...

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 2.6.32-33, download a new kernel (2.6.31-8) and its patch (xen-patch-2.6.31-10) for dom0. But after I compile xen and the new kernel, I failed...

Linux 3.11 added respective support, so I think we should follow suit. 1: xen: add LZ4 decompression support 2: libxc: add LZ4 decompression support Signed-off-by: Jan Beulich <jbeulich@suse.com>
