[Xen-users] "'Invalid kernel', 'xc_dom_find_loader: no loader found\n" with new vanilla 2.6.23-rc8

Hello Mark,

you've been absolutely right. If I do boot the newly created 2.6.23-rc8 kernel I see in the early stages an message stating: [Linux-bzImage]
So, it looks like i'am trying to boot an bzImage linux kernel.

At my linux-source directory, I've found one big vmlinux (45 MB). But this file also gives me the same error message.

If i do issue the following command, i do get the following (I've now switched to 2.6.23-rc9):
debian:/home/linux-2.6.23-rc9# objdump -j __xen_guest -s ./vmlinux

./vmlinux:     file format elf32-i386

With my 2.6.18 (default DomU) i do get the following output:
debian:/home/xen-3.1# objdump -j __xen_guest -s ./build-linux-2.6.18-xen_x86_32/vmlinux

./build-linux-2.6.18-xen_x86_32/vmlinux:     file format elf32-i386

>>What version of Xen are you running?  
I've installed the latest xen form testing. Until now: 3.1.1-rc3
Xen-tools: 3.8

>>Can you stick the kernel online
>>somewhere so others can have a go at booting it on their systems?

Currently, I've got no webpage active.

So, at this time I think the build process from vanilla kernel isn't doing the right thing.
