Pkg xen devel - May 2008 - Bug#479197: xen-hypervisor-3.2-1-amd64: hypervisor fails to load dom0 ("not an ELF binary")

Package: xen-hypervisor-3.2-1-amd64
Version: 3.2.0-5
Severity: important


The hypervisor loads OK but then fails to load my dom0 kernel.  I get
an erorr message "not an ELF binary" followed after 5s by a hypervisor
reboot.

/boot/grub/grub.cfg contains:

menuentry "Debian GNU/Linux, Xen 3.2-1-amd64, Linux
2.6.22-3-vserver-amd64 (single-user mode)" {
        set root=(hd0,1)
        multiboot (hd0,1)/xen-3.2-1-amd64.gz
        module  (hd0,1)/vmlinuz-2.6.22-3-vserver-amd64
root=/dev/mapper/mirror_a-root_fs ro single
        module  (hd0,1)/initrd.img-2.6.22-3-vserver-amd64
}
menuentry "Debian GNU/Linux, Xen 3.2-1-amd64, Linux 2.6.22-3-vserver-amd64
" {
        set root=(hd0,1)
        multiboot (hd0,1)/xen-3.2-1-amd64.gz
        module  (hd0,1)/vmlinuz-2.6.22-3-vserver-amd64
root=/dev/mapper/mirror_a-root_fs ro
        module  (hd0,1)/initrd.img-2.6.22-3-vserver-amd64
}


On the other hand, this boot configuration works, though without the
hypervisor, Xen is of course not running:


menuentry "Debian GNU/Linux, linux 2.6.22-3-vserver-amd64 (single-user
mode)" {
        linux   (hd0,1)/vmlinuz-2.6.22-3-vserver-amd64
root=/dev/mapper/mirror_a-root_fs ro single
        initrd  (hd0,1)/initrd.img-2.6.22-3-vserver-amd64
}

The kernels are from the "linux-image-2.6.22-3-vserver-amd64" package:

Is that really a xen dom0 kernel?  It doesn't like like it (it would
have -xen part)

That would confirm that this is not a dom0 kernel: dom0 kernels can't
boot without Xen.

That just looks your kernel image is wrong, not that the hypervisor is
bugged.

Many thanks for your helpful responses.     Is there a Debian AMD64
dom0 kernel at all?  Is there one in lenny?   What is it called?

James.
