RE: [Xen-devel] pv_ops dom0 testing

["Aviv Grafi" <aviv@xxxxxxxxxxxx>]

I had the same issue few days ago: try to boot the vmlinux (and not
vmlinuz) image that you can find in your kernel build directory.
You can verify that you are booting the right image file by using the
readelf tool.

Subject: [Xen-devel] pv_ops dom0 testing

I am trying to get a pv_ops dom0 working for testing, but I am running
into an elf_init error:

(XEN) *** LOADING DOMAIN 0 ***
(XEN) elf_init: not an ELF binary

Full output attached.

>From what I have read on the mailing lists, it seems
that it is usually a problem with either grub or a corrupt dom0 kernel.

Attached is my kernel config (2.6.28-rc6-tip).

I followed the instructions on:
http://wiki.xensource.com/xenwiki/XenParavirtOps

Then I did make menuconfig and added:
XEN_DOM0
XEN_BLKDEV_BACKEND

here are the two grub entries I tried

title           Xen 3.4-unstable / Ubuntu 8.10, kernel 2.6.28-rc6-tip
root            (hd0,0)
kernel          /boot/xen-3.4-unstable.gz loglvl=all guest_loglvl=all
dom0_max_vcpus=1 com1=115200,8n1 console=com1 noreboot dom0_mem=512M
module          /boot/vmlinuz-2.6.28-rc6-tip root=/dev/sda1 ro
console=tty0
xencons=ttyS0,115200
module          /boot/initrd.img-2.6.28-rc6-tip

title           Xen 3.4-unstable / Ubuntu 8.10, kernel 2.6.28-rc6-tip

module          /boot/vmlinuz-2.6.28-rc6-tip

module          /boot/initrd.img-2.6.28-rc6-tip

The error was reported by others (unanswered), but they might be
unrelated:
http://xen.markmail.org/message/grqiejrlax6tyutn?q=elf_init
http://xen.markmail.org/message/r5y32q5yyuv4okgj?q=elf_init

Any suggestions on what went wrong and/or what else to try?

Cheers,
Todd
